The United Nations' World Food Programme has said that it is unable to help one million Syrians who are going hungry and helpless due to the 22-month civil conflict.
The World Food Program (WFP) said it is helping 1.5 million Syrians, but continued fighting and an inability to use the port of Tartus to deliver food mean many people are not receiving aid.
The UN estimates that over 60,000 people have been killed in the uprising, which began in March 2011, the BBC reports.
According to the report, late 2012 saw a sharp rise in the number of attacks on WFP aid trucks, said the agency, which has also been hit by fuel shortages.
The UN estimates that around four million Syrians are in need of humanitarian aid.
Meanwhile, the UN refugee agency said the number of refugees fleeing the violence in Syria had leapt by nearly 100,000 in the past month.
According to the report, it said there were 597,240 registered refugees and individuals awaiting registration as of 6 January, up from 509,559 the month before. (ANI)
