Syria has been particularly hard hit by the decline in global humanitarian aid, especially from the US. In the northwest of the country, hundreds of thousands of displaced people are still living in makeshift shelters. When the Assad regime fell, they hoped to be able to return home. But on seeing their villages destroyed, most have remained stranded in camps, waiting for reconstruction that will take years. As time goes by, living conditions there are deteriorating and vital infrastructure such as hospitals are at risk of closing.
