U.S. and Russian military officials held talks in Geneva Friday aimed at securing a cease-fire in Syria, but the United Nations has warned it would be "extremely difficult" to monitor any deal, NBC News reported.
International powers pledged seven days ago to try to bring about a "cessation of hostilities" in Syria's five-year civil war this week, but aside from an increase in aid convoys there has been little sign of progress on the ground.
It was hoped that a temporary truce would begin by Friday, allowing the resumption of diplomatic talks in Geneva by Feb. 25. But a major practical complication is that the cease-fire would not apply to U.N.-designated terror groups including ISIS or the al-Nusra Front.
