British Prime Minister David Cameron and President Barack Obama agreed on Saturday on deterring the use of chemical weapons, and both leaders were concerned about "increasing signs" that Syria attacked its civilians, a spokesperson for Cameron said.
"They are both gravely concerned by the attack that took place in Damascus on Wednesday and the increasing signs that this was a significant chemical weapons attack carried out by the Syrian regime against its own people," the spokesperson said. "They reiterated that significant use of chemical weapons would merit a serious response from the international community and both have tasked officials to examine all the options."
Cameron and Obama were reacting to the latest horrific details to come out of Syria. Doctors Without Borders confirmed that they witnessed over 3,600 victims who were treated for exposure to at least one chemical agent. All of the victims showed signs of neurotoxicity and 355 of them had died as of August 21.
Syrian rebels maintain that forces loyal to Syrian President Bashar al-Assad launched the chemical attack. The Syrian government continues to deny that they have used any form of chemical weapon.
Obama told CNN earlier this week that the chemical attack is a "big event of grave concern" that requires American attention, stating also that it would affect "core national interests" of the United States and its allies.
U.S. defense officials told The Associated Press that the Navy had sent a fourth warship to the eastern Mediterranean Sea. The ship is capable of launching a missile into the Syrian capital and beyond. The officials spoke on condition of anonymity as they weren't authorized to divulge warship movements publicly.
A senior Syrian official stated on Saturday that any action by the U.S. would "result in a regional war that would not end favorably for the United States." Notwithstanding, Obama met with his national security advisers on Saturday to lay all options on the table including military action.
However, up to now, the White House has stayed quiet regarding military actions, preferring to supply rebel forces with non-lethal assistance while attempting to gain international support.
