WASHINGTON - Implementing a ceasefire will take time, a White House spokeswoman said on Friday as machine-gun fire, shelling and smoke were observed at the Syria-Turkey border one day after top U.S. officials announced a truce. Asked about the fighting in the region despite the pause agreement, White House spokeswoman Stephanie Grisham told Fox News in an interview that the U.S. delegation was 'successful in a ceasefire, but that takes time,' adding that she would not discuss operations on the ground.
