Secretary of State John Kerry said a US response to the chemical weapons attack in Syria would not resemble interventions in Iraq, Afghanistan or Libya.
Secretary of State John Kerry described Syrian President Assad a "thug and a murderer" and said the US would work on its on own timeline in response to the chemical weapons attack.
The US intercepted the communications of a "senior official intimately familiar with the offensive" confirming the chemical weapons attack on August 21, an intelligence report showed.
US Secretary of State John Kerry said at least 1,429 Syrian citizens, including 426 children, were killed in the chemical weapons attack.
US Secretary of State John Kerry said a US intelligence report said there was "high confidence" that the Syrian Government carried out a chemical weapons attack with nerve agent on August 21.
He added that the rockets involved in the attack only came from Government sites.
US Secretary of State John Kerry said the US knows that the Syrian Government had used chemical weapons multiple times this year.
US Defence Secretary Chuck Hagel said the Obama administration was consulting with its allies to "further develop the facts" about last week's alleged chemical weapons attack in Syria.
Speaking at a news conference in the Philippines this morning, Hagel said the administration also would continue to seek input from members of Congress on how the US should respond to the deadly attack.
The Obama administration will release a declassified intelligence report that links the Syrian regime to chemical weapons use later today, according to CBS News' Chief White House Correspondent Major Garrett.
Without naming his sources, he wrote on Twitter:
Obama administration to release declassified intelligence report on Syria chemical weapons attack on Friday.
Obama administration will release legal finding for military action when/if POTUS orders it.
The US and its allies have "no smoking gun" proving Syrian President Assad personally ordered his forces to use chemical weapons to attack suburbs of Damascus, US national security officials said.
In secret intelligence assessments and a still-unreleased report summarising US intelligence on the alleged gas attack on August 21st, US agencies express high confidence that Syrian government forces carried out the attack.
However the evidence does not prove that Assad himself ordered that chemical munitions be used, according to the officials, who spoke to Reuters on condition of anonymity.
The Joint Intelligence Committee said its conclusion that it is "highly likely" that the Syria regime carried out last week's chemical attacks near Damascus is based on a "limited but growing body of intelligence".
"The JIC had high confidence in all of its assessments except in relation to the regime’s precise motivation for carrying out an attack of this scale at this time – though intelligence may increase our confidence in the future," a JIC report added.
In response to claims by the Assad regime that Syrian rebels faked the attacks, the JIC said: "There is no credible intelligence or other evidence to substantiate the claims or the possession of (chemical weapons) by the opposition."
