The United Nations' World Food Program said Tuesday that in the coming six months 6.5 million civilians inside Syria will need food aid to survive.

There are areas in Syria that have gone months without receiving any type of aid because humanitarian organizations cannot get access there, WFP spokeswoman Elisabeth Byrs said in Geneva.

Insecurity in the provinces of Al-Raqqa and Deir-Ezzor prevented dispatches by road to these areas in December for the second consecutive month, she said.

The U.N. agency also expressed its concern over the populations of towns that are currently under siege and where it is believed that the food situation is critical.

"WFP is gravely concerned about people who live in areas under siege. Their nutrition situation is expected to have deteriorated significantly," Byrs told reporters.

The WFP has tried several times without success in recent months to get into the besieged zones inside and around Damascus, she said.

Elsewhere in the country, the WFP managed to deliver enough food in December to feed 3.8 million people.

Now, the WFP is increasing its logistical and operational capabilities and to be able to feed 4.25 million people this month, although its goal for this year is to guarantee that it can feed a total of seven million Syrians.

This last figure includes almost three million refugees in neighboring countries.

The financial requirements for this enormous operation amount to some $2 billion.

The WFP needs to collect $35 million per week to be able to respond to the food needs of the population after three years of a civil war that has claimed more than 100,000 lives. EFE
