Syria's Idlib at Risk of Humanitarian Disaster Margaret Besheer UNITED NATIONS - The U.N. humanitarian chief warned Tuesday the Syrian province of Idlib is at risk of becoming "the worst humanitarian disaster the world has seen so far this century," as Russian-backed Syrian government forces continue a campaign against one of the last rebel hold outs. "For more than 90 days now, bombing and shelling by the government of Syria, backed by the Russian Federation, has produced carnage in the so-called de-escalation zone of Idlib," Mark Lowcock told a meeting of the U.N. Security Council. He said at least 450 civilians have been killed since late April, including more than 100 just in the past two weeks. More than 440,000 have been displaced, many for the fourth or fifth time. .
