- Sicilian Berbers in Agrigento revolt and depose the independent Emir Ahmed ibn Khorob. They offer Sicily to the Fatimid Caliphate in Ifriqiya (modern Tunisia). Caliph Abdullah al-Mahdi Billah welcomes this turn of events, but refuses to grant the Berber rulers their autonomy. He sends a Fatimid expeditionary force under Abu Said Musa which lands in Sicily and, with some difficulty, takes control of the island. Abdullah al-Mahdi Billah appoints Salam ibn Rashid as the emir of Sicily. Ahmed ibn Khorob is dispatched to Raqqada and executed.
