Displacements From Syria's Idlib Hit Record Levels Margaret Besheer UNITED NATIONS - The United Nations said Friday that more than 140,000 civilians have been displaced from northwestern Syria in just the last three days. An escalation in fighting across Idlib and Aleppo has pushed more than 830,000 people to flee their homes since early December, causing what the U.N. has said is the biggest humanitarian catastrophe since the conflict started in 2011. Some 3 million people live in the province. "Women and children are among those that are suffering the most -- they make up about 81% of the recently displaced people," U.N. spokesman Stephane Dujarric told reporters. "Temperatures across northwest Syria have been below freezing for several days, leaving families exposed to increasingly harsh conditions." Many of the displaced are moving north toward already overcrowded camps near the Syria-Turkey border. They are fleeing an escalation in fighting between the Syrian military, which is backed by Russia and Iran, and Syrian armed opposition groups, some of whom have Turkish support. The Syrian government is trying to crush the last major opposition strongholds. .
