MORE than $4 billion (£3.17 bn) in life-saving aid is needed for more than 10 million Syrians facing a largely forgotten crisis, the United Nations warned today.

UN Office for the Co-ordination of Humanitarian Affairs Syria co-ordinator Adam Abdelmoula said that the situation in the country remains “one of the most deadly to civilians in the world.”

He made the appeal days after Syria marked the 13th anniversary of a war that has killed nearly a half million people and left large parts of the country destroyed.
