GENEVA (Reuters) - Medecins Sans Frontieres (Doctors Without Borders) said on Tuesday it had suspended most of its medical aid activities in northeast Syria and was evacuating all international staff in the wake of air strikes and violence during Turkey's week-old incursion.

"The decision to suspend the majority of MSF’s activities comes as the humanitarian situation spirals further out of control and needs are likely to increase," MSF said in a statement that followed another aid group Mercy Corps suspending its aid work on Monday
