Khan Shaykhun chemical attack
The Khan Shaykhun chemical attack took place on 4 April 2017 on the town of Khan Shaykhun in the Idlib Governorate of Syria. At the time of the attack, the town was under the control of Tahrir al-Sham, previously known as the al-Nusra Front.
|2017 Khan Shaykhun chemical attack|
|Part of the Syrian Civil War|
|Type||Airstrike, sarin attack|
|Location||Khan Shaykhun, Idlib Governorate, Syria
|Date||4 April 2017
06:30 EEST (UTC+03:00)
|Executed by||Syrian Arab Air Force|
The town was reported to have been struck by an airstrike by government forces followed by massive civilian chemical poisoning. The release of a toxic gas, which included sarin, or a similar substance, killed at least 74 people and injured more than 557, according to the Idlib health authority. The attack was the deadliest use of chemical weapons in the Syrian civil war since the Ghouta chemical attack in 2013.
The OPCW-UN Joint Investigative Mechanism,the governments of the United States, United Kingdom, Turkey, Saudi Arabia, France, and Israel, as well as Human Rights Watch have attributed the attack to the forces of Syrian President Bashar al-Assad. The Assad government denied using any chemical weapons in the air strike. The Russian Defense Ministry stated that Syrian aircraft had bombed a warehouse belonging to rebels which "may have contained a rebel chemical arms stockpile".
Use of chemical weapons in the Syrian Civil War has been confirmed by the local sources in Syria and by the United Nations. Deadly attacks by chemical weapons during the war include the Ghouta attack in the suburbs of Damascus in August 2013 and the Khan al-Assal attack in the suburbs of Aleppo in March 2013. While no party took responsibility for the chemical attacks, a U.N. fact-finding mission and a UNHRC Commission of Inquiry have both investigated the attacks.
The U.N. mission found likely use of the nerve agent sarin in the case of Khan al-Asal (19 March 2013), Saraqib (29 April 2013), Ghouta (21 August 2013), Jobar (24 August 2013) and Ashrafiyat Sahnaya (25 August 2013). The UNHRC commission later confirmed the use of sarin in the Khan al-Asal, Saraqib and Ghouta attacks, but did not mention the Jobar and the Ashrafiyat Sahnaya attacks. The UNHRC commission also found the sarin used in the Khan al-Asal attack bore "the same unique hallmarks" as the sarin used in the Ghouta attack and indicated the perpetrators likely had access to chemicals from the Syrian Army's stockpile. Those attacks prompted the international community to pressure disarmament of the Syrian Armed Forces from chemical weapons, which was executed during 2014. Despite the disarmament process, dozens of incidents with suspected use of chemical weapons followed throughout Syria, the majority being attributed to anti-government fighters, in particular the Al Qaeda affiliate Al Nusra Front.
In August 2016, a United Nations report explicitly blamed the Syrian military of Bashar al-Assad for dropping chlorine bombs on the towns of Talmenes on 21 April 2014 and Sarmin on 16 March 2015. Several other attacks have been alleged, reported and/or investigated. In December 2016, at least 53 people were killed in an alleged chemical weapons attack in ISIL-held villages near Uqairabat that bore similarities to the Ghouta attack, with none of the dead having blast injuries. On 30 March 2017, an airstrike hit the town of al-Lataminah in the northern Hama Governorate, around 15 kilometers (9 miles) from Khan Shaykhun. More than 70 people in the area were then exposed to an unidentified chemical agent and showed symptoms of nausea, agitation, foaming, muscle spasm, and miosis (constriction of the pupil of the eye). Cardiac arrest occurred in two of the victims and an orthopedic doctor died. On 3 April 2017, one day before the attack, a "regime aircraft" allegedly carried out a similar chlorine gas attack on Al-Habit, a nearby village, injuring dozens and killing two children.
The attack took place around 6:30 a.m. local time on 4 April, before most children and parents had left for school or work. Witnesses reported smelling a strange odor about ten minutes after a rocket attack and airstrike, followed by visible symptoms of poisoning. White Helmet workers reported four unusually weak explosions. Medical workers and witnesses said the attack was different than the chlorine gas attacks they had experienced in the past, in which the chlorine gas usually killed a few people in confined spaces and buildings. In contrast, in this attack, many people died outside. Furthermore, the victims exhibited pinpoint pupils, a sign of contact with nerve agents and sarin specifically. Other symptoms reported included coldness in the extremities, decreased heart rate, and low blood pressure. Some first responders became ill when they came into contact with the victims. According to the Turkish health ministry, medical tests have confirmed the presence of isopropyl methylphosphonic acid—a known byproduct of sarin reacting with other compounds—in blood and urine samples of the victims. Tests by British scientists of samples found at the scene indicated the chemical involved was "sarin or a sarin-like substance".
Kareem Shaheen, the first western journalist to visit the town after the attack, photographed the crater where the chemical weapon was reported to have hit and saw an apparently abandoned warehouse and silos near the crater.
Medical sources in Idlib in the immediate aftermath of the attack reported more than 58 people, including 11 children, were killed and over 300 were wounded. Test results of samples collected from ten of them indicated they had been exposed to sarin or a sarin like substance.
By 7:30 a.m. EEST 100 wounded people arrived at a local field hospital. Minister of health, Mohamad Firas al-Jundi, said victims experienced suffocation, fluid in the lungs, foaming at the mouth, unconsciousness, spasm, and paralysis. A few hours after the attack, a nearby clinic treating victims was hit by an airstrike, with reports that Russians bombed the hospital with the victims in an attempt to destroy the evidence. The area's largest hospital was bombed two days prior. According to Dr. Abdel Hay Tennari, who treated 22 victims of the attack, the symptoms of victims correspond to symptoms of exposure to sarin. Patients who received pralidoxime, an antidote of sarin, reportedly stabilized their medical state in around an hour. Médecins Sans Frontières visited Bab Al Hawa hospital where they determined symptoms consistent with sarin. They also visited other hospitals where victims were taken and reported, "that victims smelled of bleach, suggesting they had been exposed to chlorine." They concluded that the "reports strongly suggest that victims of the attack on Khan Sheikhoun were exposed to at least two different chemical agents."
On 5 April, local doctors and rescue workers at the scene said the number of dead had risen to 74, with 600 injured, while Turkish President Recep Tayyip Erdoğan and French Ambassador to the United Nations François Delattre said over 100 had died. Rescue workers gathered soil and tissue samples and sent them to Western intelligence officials for analysis. On 6 April, the Turkish Ministry of Health, which had conducted tests on people transported to Turkey, said it had identified the chemical used in the attack as sarin, citing lung damage found in victims.
On 6 September 2017, the Office of the United Nations High Commissioner for Human Rights's Independent International Commission of Inquiry on the Syrian Arab Republic concluded that a Syrian Arab Air Force aircraft was responsible for dropping the sarin during the attack. This finding was confirmed in a report released on 26 October 2017 by the OPCW-UN Joint Investigative Mechanism.
Many governments, such as the United States and some European countries and the Gulf Cooperation Council have attributed the attack to the Syrian government. According to investigation by Human Rights Watch, the attack was conducted by Syrian government forces from the air using Soviet-made KhAB-250 aerial bombs designed to deliver sarin. Syria has denied any involvement. Immediately following the attacks, Russia argued that the deaths were a result of gas released when a government airstrike hit a rebel-operated chemical weapons factory, and following the OPCW conclusions, in October of 2017, it strongly disputed the conclusion that the Syrian government was responsible. The UN Security Council session unanimously declared the need for an investigation of the chemical attack. According to an OPCW report, an investigation into the attack was concluded and released on 29 June 2017, which confirmed the use of sarin gas, or a similar substance.
The United Kingdom’s assessment is that it is almost certain that the Syrian Government was responsible for a sarin attack on Khan Shaykhun on 4 April. (...) There is no evidence to suggest that any party to the conflict in Syria, other than the Syrian Government, has access to a complex nerve agent such as sarin. We note that the FFM’s report refers to testimony from witnesses describing the presence of jets in the area at the time of the attack. Only the Syrian Air Force has the capability to launch a chemical weapons attack from aircraft, and it has already been condemned by this Council for having been found to have used chemical weapons, deployed from aircraft, on at least three occasions in 2014 and 2015.— Sir Geoffrey Adams, UK Permanent Representative to the OPCW, 
Claims by the Syrian government, Syrian opposition and Russian governmentEdit
Syrian opposition claimsEdit
According to the Idlib Media Centre, the chemical agent had the characteristics of sarin. The National Coalition for Syrian Revolutionary and Opposition Forces accused the Syrian government and the Syrian Armed Forces of carrying out the attack and called for an immediate investigation by the United Nations Security Council. The opposition groups said the Syrian air force dropped chemical bombs on a civilian population.
Syrian government claimsEdit
The position of Syrian government changed on numerous occasions. On the day of the attack, a Syrian government official told Reuters "the government does not and has not used chemical weapons, not in the past and not in the future." The pro-government Al-Masdar News cited an army source as saying it had attacked a missile factory in the town using Sukhoi Su-22 bombers, whose bombs Al-Masdar News says cannot be filled with any chemical substances, and did not know the factory contained chemicals. The use of Sukhoi Su-22 aircraft in the attack was also noted by pro-rebel sources (SOHR). Later, the Russian Ministry of Defence reiterated the statement made by the Syrian Armed Forces, but said the attack on the ammunition depot took place between 11:30 and 12:30 EEST.
In an April 13 interview to AFP, President Assad said the attack is "100 per cent fabrication" by the United States "working hand-in-glove with the terrorists", intended to provide a pretext for the airstrike on the Shayrat Airbase. Assad stated: "You have a lot of fake videos now… We don’t know whether those dead children were killed in Khan Sheikhun. Were they dead at all?” According to numerous eyewitnesses and reporters on the ground, children did in fact die in the attack.
Walid Muallem, the Syrian foreign minister told journalists at a press conference in Damascus their armed forces "did not and will not" use chemical weapons, even against "terror groups" fighting against the Syrian government. He also said "the first reports of the chemical attack appeared several hours before the government airstrike, indicating that the chemical attack may have been a cruel and cynical 'false flag' operation used by the jihadists in a bid for US support." Muallem also promised to provide information to the Organisation for the Prohibition of Chemical Weapons (OPCW) and the United Nations regarding the transfer of chemical substances from Iraq to Syria, or from Turkey to Syria.
In fact, the samples collected by Syrian government officials and later passed to OPCW tested positively for sarin.
Russian government claimsEdit
The Russian government denied involvement in the chemical attack; Russia's defence ministry issued a statement saying the Russian Air Force had "not carried out any strikes near Khan Shaykhun of Idlib province", but said a Syrian aircraft did conduct an airstrike on a warehouse containing ammunition and equipment belonging to rebels near Khan Shaykhun, "yesterday, from 11:30 a.m. to 12:30 p.m". The Russian Foreign Ministry said it was "premature to accuse the Syrian government of using chemical weapons in Idlib", and insist on full and impartial investigation. Shortly after the attack Russian presidential spokesman Dmitry Peskov told reporters the use of chemical weapons is a "dangerous and monstrous crime" and that Russia's support for Assad is not "unconditional". He also said he doubted information was based on "objective materials or evidence", and that only Syrian government can resist "terrorists on the ground."
Later, President Vladimir Putin said the attack could be a provocation, but that several versions were possible, and the UN should investigate the attack. On April 11, Putin suggested the chemical attack was a false flag operation intended to discredit the Syrian government. On April 14, Russian Foreign Minister Sergei Lavrov said there was "growing evidence" the attack was staged. In May 2017, Vladimir Putin of Russia stated categorically that the other governments accusing the Syrian government was but a "provocation" and that Syria′s president Bashar Assad had not used chemical weapons.
However, British journalist Eliot Higgins has shown that the Russian claims that a warehouse containing chemical weapons was bombed were made "two to three hours" after the first images of victims appeared, while other images from the chemical attack were posted online before the supposed airstrike on the warehouse. Russia's claims were also criticised by Dan Kaszeta, a veteran of the US Army Reserve's Chemical Corps, who called Russia's statement "an infantile argument", and by the anti-Kremlin Russian non-profit Conflict Intelligence Team.
Russia has agreed that "sarin or sarin-like substance was used," but has consistently stated that there is no proof that the Syrian government was responsible. Following the release of the UN committtee's report, Russia was harshly critical, arguing that the report was "flawed and logically inconsistent," saying that it relied on "questionable witness accounts and unverified evidence," and that "investigators never visited the site of the incident."
United States reactionEdit
According to the US government, the Syrian government under Assad was behind the chemical attack, and Syrian jets carried out the bombing of a rebel stronghold. U.S. Secretary of State Rex Tillerson was quoted as saying "Either Russia has been complicit or Russia has been simply incompetent". According to Tillerson, the U.S. appealed to Assad to cease the use of chemical weapons, and "[o]ther than that, there is no change to our military posture", with ISIS remaining the primary priority.
President Donald Trump called the attack "reprehensible" and attributed it to the Syrian government, saying the act could not be ignored "by the civilized world" during his meeting with King Abdullah II of Jordan. Trump also blamed the attack on supposed failures of the administration of his predecessor, Barack Obama. U.S. Secretary of State Rex Tillerson said: "Anyone who uses chemical weapons to attack his own people shows a fundamental disregard for human decency and must be held accountable." US representative to the UN Nikki Haley has stated that, though before the chemical attack the US had not considered overthrowing Syrian President Bashar al-Assad from power a top US priority, it is now prominent among US priorities in the region. At the UN Security Council, Haley said "When the United Nations consistently fails in its duty to act collectively, there are times in the life of states that we are compelled to take our own action", by it implying if the UN failed to hold Assad accountable for the use of chemical weapons on civilians, the US will. CIA Director Mike Pompeo confirmed on Thursday 13 April that his agency concluded the Syrian government was responsible for the chemical attack in Khan Shaykhun. “We were good and fast,” Pompeo said. The top Democrat on the house intelligence committee, Rep. Adam Schiff, agreed that the Assad government was responsible for the attack.
A few members of Congress and former officials expressed skepticism, like Democratic Congresswoman Tulsi Gabbard, Republican Congressman Thomas Massie, and former Republican Congressman Ron Paul.
On the morning of 7 April 2017, 72 hours after the attack, the United States launched 59 cruise missiles on Shayrat Airbase, a Syrian airfield near Shayrat, believed to be the base for the aircraft that carried out the chemical attack. In contrast to the coalition's accidental air raid on Deir ez-Zor in 2016, this was both a unilateral action and the first intentional strike against the Syrian government.
On 24 April 2017, the United States Department of the Treasury imposed sanctions on 271 employees of the Syrian Scientific Studies and Research Center for their alleged role in producing chemical weapons.
Supranational and non-governmental organizationsEdit
Secretary-General António Guterres said he was "deeply disturbed" by reports of the Idlib chemical attack, noting that the use of chemical weapons is banned under international law. Federica Mogherini, the European Union's diplomatic chief, called the attack "awful" and said Bashar al-Assad's government bore "primary responsibility" for it.
The Organisation for the Prohibition of Chemical Weapons (OPCW) expressed "serious concern" and said its Fact-Finding Mission in Syria was "gathering and analysing information from all available sources." The following day, the Technical Secretariat of the OPCW, referring to the media reports, requested all member states of the Chemical Weapons Convention to share available information on what it described preliminary as "allegations of use of chemical weapons in the Khan Shaykhun area of Idlib province in the Syrian Arab Republic." Amnesty International said the evidence points to an "air-launched chemical attack", while the World Health Organization said victims carried the signs of exposure to nerve agents. On October 26, an investigative panel created by the UN Security Council said it was “confident” that Assad’s air force was behind the chemical attack. Further, that the attack was possible because it drew from old Syrian stockpiles that Assad had vowed to destroy in 2013, indicating that Damascus has systematically cheated international inspectors for the past four years.
UN Security Council countriesEdit
France called for an emergency meeting of the United Nations Security Council after the attack. France, Britain, and the United States (who are among the permanent members of the Security Council), circulated a draft to the Council's 15 members condemning the attack in Syria and demanding a full investigation into it. The emergency closed-door meeting was set on 5 April in New York. United States Ambassador to the United Nations Nikki Haley, serving as president of the Security Council for the month, announced there would not be a vote on a draft resolution to respond to the chemical weapons attack, but instead of one resolution by the U.S. and a second resolution by Russia, there was a third resolution unexpectedly submitted by Sweden and nine other non-permanent members. When the council concluded its meeting without conclusion on the morning of 6 April, the U.S. launched a missile strike. On 12 April, the proposed draft resolution was vetoed by Russia as it attributed blame to the Syrian government before any investigation had been undertaken. This was the eighth time that Russia vetoed a Security Council resolution on Syria. Instead, on April 20, Russia and Iran formally proposed to start an OPCW investigation (which was rejected as an investigation is already in progress) and then on April 26 blocked UN resolution calling Syria to disclose information for the first OPCW investigation at the same accusing UN of "blocking independent international investigation" earlier proposed by Russia and Iran.
On April 26, 2017, French Foreign Minister Jean-Marc Ayrault said France had concluded that the Syrian government was "unquestionably" the perpetrator of the attack. He added that the same mixture of sarin and hexamine had been used in the 2013 Saraqib chemical attack.
United Kingdom government defense minister, Michael Fallon said he believed the Syrian air force responsible for the attack. Opposition leader Jeremy Corbyn said "There should now be an immediate ceasefire and a UN-led investigation rapidly into what is a horrific and totally illegal action by somebody using chemical weapons against innocent people."
The Egyptian Foreign Ministry released a statement saying the "painful and unacceptable" images of the massacre reaffirm the necessity of reaching a political solution to end the crisis in Syria, in light of the international community decisions and Security Council Resolution 2254, as well as the Geneva Conventions.
Iranian President Hassan Rouhani called for an "impartial international fact-finding body" to be set up to investigate the attack. Foreign minister Mohammad Javad Zarif described the incident as "very painful" and condemned it, but also criticized US for attacking the Syrian airbase "without any investigation". Iranian Foreign ministry spokesman Bahram Ghassemi condemned "all use of chemical weapons," but suggested the blame for the attack lay with "terrorist groups" rather than the Syrian government.
Canadian Prime Minister Justin Trudeau said: "There are continuing questions ... about who is responsible for these horrible attacks against civilians, and that's why I'm impressing on the UN Security Council to pass a strong resolution that allows the international community to determine first of all who was responsible for these attacks and how we will move forward." Israeli Prime Minister Benjamin Netanyahu called on the international community "to fulfill its obligation from 2013 to fully and finally remove these horrible weapons from Syria". Other countries who condemned the chemical attack include the Czech Republic, Italy, Pakistan, Saudi Arabia, Switzerland, United Kingdom, and the Vatican City.
The Iraqi government condemned the chemical attack and called for an "initiative aimed at punishing those responsible". The next day, Iraqi cleric Muqtada al-Sadr also condemned the attacks and called for President Assad to step down. Australian Prime Minister Malcolm Turnbull said if al-Assad was found to be behind the attack, as the United States believe, it represented "a shocking war crime." Other countries who accused Assad for responsibility include Qatar and Turkey.
Former head of the International Atomic Energy Agency (IAEA), Hans Blix, described the US retaliation as "measured" and specific, but later criticized the rapid American military response. He initially raised concern that the responsibility of the Syrian government was not yet proven, but stated on April 11, 2017, "On balance it seems probable that the attack with gas was undertaken by the Syrian government air force," adding that "the factual circumstances known so far do not point to the rebels as arranging the gas action".
Other people who have expressed skepticism of the Syrian government being responsible for the attack include former UN weapons inspector Scott Ritter, MIT professor emeritus Theodore Postol, former UK ambassador to Syria and director of the British Syrian Society Peter Ford, investigative Israeli journalist Uri Avneri, and investigative journalist Seymour Hersh. The OPCW-UN JIM report found no merit in any of these views and concluded that the sarin used in the attack bore the Syrian regime's signature.

No one disputes the fact that a Syrian air force SU-22 fighter-bomber conducted a bombing mission against a target in Khan Sheikhoun on the morning of April 4, 2017.
