The UN World Food Program on Tuesday said it was airlifting supplies to northeastern Syria, where raging violence has made it nearly impossible to truck aid in.

"WFP started airlifting on Tuesday enough food to feed close to 30,000 displaced people for a month from Iraq to Qamishli in northeast Syria," spokeswoman Elisabeth Byrs said.

The agency plans to fly in more than 400 tons of food and other items, mainly clothes, detergent and soap, supplied by UN children's agency UNICEF and the International Organization for Migration.

Aid agencies have repeatedly sounded the alarm about their inability to supply regular aid by road -- logistically simpler, but more dangerous -- to the millions of Syrians who have been driven from their homes over nearly three years of civil war.

The top three donors to date to the humanitarian crisis in some regions of Syria have been the United States with $92 million, Britain with $49 million and the European Commission with $14 million.
