WASHINGTON (AP) — Now that the Obama administration has seen evidence that Syria's Bashar Assad has twice used sarin gas on his own people, there's renewed pressure for the U.S. to take additional action to help Syria's rebels.
President Barack Obama had said the use of chemical weapons was a "red line" that Assad shouldn't cross.
U.S. military commanders have laid out a range of possible options -- including the establishment of a no-fly zone or a secured area within Syria.
There could also be airstrikes by drones and fighter jets -- and even the use of ground forces to secure chemical weapons supplies.
