More than 70 Syrian military trucks left Lebanon overnight, witnesses said on Friday, carrying tanks, mortars and anti-aircraft guns as Damascus raced to complete its withdrawal by the end of the month. Syria pledged to pull out by April 30. The Associated Press quoted Witnesses as saying that Syrian forces, now in the final phase of withdrawal, abandoned two posts in the mountainous Dahr al-Baydar area east of Beirut and another in the Bekaa Valley. Syria began withdrawing its 14,000 troops and dismantling intelligence posts on March 8, in line with a U.N. Security Council resolution demanding that foreign forces leave.
