The US now has "little doubt" the Syrian government used chemical weapons against civilians last week, a senior reporter told Reuters. The Obama administration said a "serious response" would be required should evidence of such an attack emerge.
US Senator John McCain said Washington should take "serious action" against Syria, and suggested launching cruise missiles. Speaking in South Korea, he said:
"We know for sure that he's used them at least once, now here is the second time, horrific, horrific.
"And if the United States stands by, and doesn't take very serious action, not just launching some cruise missiles, then again, our credibility in the world is diminished even more, if there is any left. "
The United States now has little doubt the Syrian government used chemical weapons against civilians last week, a senior official told Reuters.
Based on the reported number of victims, reported symptoms of those who were killed or injured, witness accounts, and other facts gathered by open sources, the U.S. intelligence community, and international partners, there is very little doubt at this point that a chemical weapon was used by the Syrian regime against civilians in this incident.
The official added that the president was now focused on "assessing the facts" to enable him to make an informed decision as to how to respond.
We are continuing to assess the facts so the president can make an informed decision about how to respond to this indiscriminate use of chemical weapons.
Gulf-based supporters have sent a 400-ton shipment of arms to Syria's outgunned rebels, one of the biggest to reach them in their two-year-old uprising, opposition sources said on Sunday.
The consignment - mostly ammunition for shoulder-fired weapons and anti-aircraft machine guns - came into northern Syria via the Turkish province of Hatay in the past 24 hours, and was already being handed out, the sources added.
One rebel officer told Reuters the flow of arms bound for rebels had increased since opposition groups accused the government of launching deadly chemical weapons attacks in Damascus on Wednesday.
