US withdrawal from Syria will pose enduring threat from IS: Top general

A top U.S. general warned on Tuesday that Islamic State would pose an enduring threat following a planned U.S. withdrawal from Syria, saying the militant group retained leaders, fighters, facilitators and resources that will fuel a menacing insurgency.

The remarks by U.S. General Joseph Votel, head of the U.S. military's Central Command, represent the latest warning by current and former U.S. officials about the risk of a resurgence by Islamic State following a planned U.S. withdrawal from Syria ordered in December by President Donald Trump.

"We do have to keep the pressure on this network. ... They have the ability to come back together if we don't," Votel told a Senate hearing. He added that territory under Islamic State's control had been reduced to less than 20 square miles (5,180 hectares) and would be recaptured by U.S.-backed forces prior to the U.S. withdrawal.
