With the war in Syria headed for a sixth year, UN agencies on Tuesday appealed for $7.73 billion in funding to help 22.5 million people affected by the conflict, AFP reports.

The appeal for funds from UN member-states covers help for 13.5 million Syrians displaced inside the war-wracked country and 4.7 million who have fled across the border to neighboring countries.

The aid will also reach some four million people in Turkey, Jordan and Lebanon who are hosting millions of Syrian refugees, said a UN statement.
