The World Food Program aims to feed 2.5 million Syrians next month, up from 1.7 million today, as more Syrians are displaced by their country's civil war and the economy is disintegrating, AP quoted a spokeswoman as saying Friday. Since the start of the Syria conflict two years ago, nearly 4 million of Syria's 22 million people have been driven from their homes by the fighting, according to U.N. estimates. This includes those who fled to neighboring countries and some 2 million who sought shelter inside Syria. In one recent wave, more than 20,000 families fled fighting in the northeastern Raqqa province, seeking refuge in the neighboring district of Deir el-Zour, according to the World Food Program. The U.N. agency said that in recent days it distributed food to some 20,000 people in public shelters in Deir el-Zour. More food trucks are to deliver food there Friday. Earlier this week, Syrian rebels completed their capture of the provincial capital of Raqqa after several days of fighting. The takeover marked the first time rebels seized a major Syrian city. Raqqa has a population of about 500,000. In addition to the internally displaced, Syrians who remain in their homes are also in increasing need of food aid, the agency said. The Syrian economy has been hit hard by the two-year-old conflict, and basics such as food and fuel are becoming scarce in many areas.
