By mid-2014, OCHA estimated that 10.8 million of Syria's 22 million population was affected by the conflict and in need of humanitarian assistance, including 6.5 million internally displaced, often multiple times - 50 per cent more than in 2013. If a comprehensive political solution is not reached, the number affected is expected to grow in 2015.

Syria is hosting more than 33,000 asylum-seekers and refugees mainly from Iraq, with smaller numbers coming from Afghanistan and Somalia. Though a significant decrease from previous years, this trend may be reversed in 2015 if there are any new arrivals of Iraqi refugees. In August 2014, approximately 95,000 people displaced by violence in Iraq entered the north-eastern Hassakeh governorate, although the majority proceeded onwards to the Kurdistan region to seek safety.

With no political solution in sight and military confrontation continuing, the number of people affected by internal conflict in the Syrian Arab Republic (Syria) was likely to increase in 2015.
