UN relief coordinator Stephen O'Brien said today that "for the immediate needs of 2017 we need about USD 8 billion." Nearly 400,000 people have been killed, and half of Syria's population displaced, by the six-year conflict.
UN agencies estimate war damages across Syria at USD 350 billion.
Earlier this week, at least 58 people were reported killed, including 11 children, in a suspected chemical attack in a town in northern Syria.
