In Lebanon, aid groups are warning of an ongoing humanitarian crisis in a Palestinian refugee camp where Islamic militants have been fighting the Lebanese army.

U.N. refugee agency director Richard Cooke: “We have been extremely concerned about the humanitarian situation of the refugees, obviously, ever since Sunday morning. But particularly we are concerned about those that remain in Nahr al-Bared camp. We have been seeing a continuous flow of people out of the camp since Tuesday evening. And so now we have, we believe, in the region of 24,000 or 25,000 of the inhabitants have left the camp.”

Some 10,000 people remain behind amidst shortages of vital supplies. Sporadic clashes have resumed since both sides reached a truce last week.
