The United Nations says it is examining Syria’s declaration yesterday that it has withdrawn the last of its soldiers and intelligence agents from Lebanon on Tuesday, ending a 29-year military presence in its small neighbor. But the US and other powers say Syria has not withdrawn a significant part of its intelligence presence. In September, the Security Council passed a resolution calling for foreign forces to be withdrawn from Lebanon. A UN team has just gone to Lebanon to verify the withdrawal of all Syrian troops, military assets and intelligence.
