Obama studies Syria options, consults UK's Cameron

President Barack Obama and his top military and national security advisers hashed out options on Saturday for responding to the alleged use of chemical weapons in Syria amid "increasing signs" that the government used poison gas against civilians.

Obama spoke with British Prime Minister David Cameron, a top US ally, and agreed that chemical weapon use by Syrian President Syrian President Bashar al-Assad's forces would merit a "serious response," a spokesperson for the prime minister said in a statement. (Reuters)
