As the conflict in Syria enters its fifth year, a political solution is still to be found. Humanitarian needs in Syria have increased significantly since the beginning of the crisis, with 12.2 million people in need of humanitarian assistance, including more than 5.6 million children. Over 220,000 people have been killed and more than 1 million injured since 2010. Many Syrians have been forced to leave their homes, often multiple times, making Syria the largest displacement crisis in the world with 7.6 million people internally displaced and almost 4 million people registered as refugees in neighboring countries. An estimated 4.8 million people are in need of humanitarian assistance in hard-to-reach areas and besieged locations. Palestine refugees are particularly vulnerable with an estimated 460,000 people receiving regular assistance around Syria School attendance has dropped by more than 50 per cent and roughly one-quarter of schools have been damaged, destroyed or are used as collective shelters. More than half of Syria's hospitals have been destroyed or badly damaged. Water supply has decreased to less than 50 per cent of its pre-crisis levels. An estimated 9.8 million people are considered food insecure and many more are living in poverty.
