BEIRUT/GENEVA (Reuters) - A Syrian or Russian air strike was reported to have killed at least 19 people and possibly many more at a market in northwestern Syria on Monday, straining a cessation of hostilities agreement meant to pave the way for peace talks.
In a further upsurge in violence, al Qaeda's Nusra Front and other Islamist insurgents not included in the U.S.-Russian agreement attacked government forces in a neighbouring province, taking over a village and at least two hilltops in their first advance for some time in the area, a monitoring group said.
