Insurgents killed 50 people in a new day of carnage in Iraq on Sunday, including 23 members of a non-Muslim minority dragged from a bus and gunned down by the roadside, security officials said. The non-Muslims from Iraq’s Yazidi minority were ambushed near the main northern city of Mosul, police Brigadier General Mohammed el-Waqa’a said. “Workers were travelling back from a textile plant in Mosul to their home in Bashika, east of the city,” he said. “Several gunmen stopped the buses, chose the Yazidi among the passengers and killed them in front of everybody.”Police said a group of cars blocked the road in the Al-Nur neighbourhood in the east of the city, while others set up a cordon to protect the gang that stormed the convoy. The captives were executed on a field by the road. Three wounded Yazidis survived, officers said.
