Around 800 people were killed in four days of sectarian clashes in Syria. Insurgents loyal to the former regime launched a series of attacks across the Alawite heartlands. In response fighters close to Ahmed al-Sharaa, Syria’s interim president, along with jihadist factions, advanced into the region. Videos posted online appear to show evidence of atrocities by pro-government fighters. Mr Sharaa said a committee would investigate the violence and report back within 30 days.
