SAWRAN, Syria — The United States and other international donors are spending hundreds of millions of dollars on humanitarian aid for Syrians afflicted by the civil war. But here in the rebel-controlled north, where the deprivation is most acute, that money has bought mostly anger and resentment: the vast majority of aid is going to territory controlled by President Bashar al-Assad, and the small amount reaching opposition-held areas is all but invisible.
Rebels argue that the humanitarian assistance is in effect helping Mr. Assad survive the war of attrition. “Aid is a weapon,” said Omar Baylasani, a rebel commander from Idlib, speaking during a visit to a Turkish border town. “Food supply is the winning card in the hands of the regime.”
