At midnight, a shooting occurs aboard an Akula-classnuclear-poweredattack submarine of the Russian Navy docked in the northern Russian port-city of Severomorsk. The shooter, Alexander Kuzminykh, a 19-year-old seaman from St. Petersburg, opened fire after murdering a soldier (who was supervising his detention on punishment charges in the personnel quarters of the submarine) with a chisel, and taking his AK-74Ucarbine. After killing five people and wounding one with the dead soldier's weapon, he proceeded to take 2 fellow soldiers hostage, and barricaded himself in the submarine's torpedo room, where he would later murder them. For 23 hours, doctors, relatives, and a priest attempt to persuade him to surrender, but to no avail. After threatening numerous times to set the torpedo room on fire (an event the authorities feared would cause a quote "second Chernobyl"), the crisis came to an end on the morning of 12 September, when a special anti-terrorist commando unit of the Russian Federal Security Service (FSB) launched a raid on the torpedo room during which, Kuzminkykh allegedly committed suicide, contrary to prior reports that he'd been killed by the unit.
