The White House just released this document, titled "U.S. Government Assessment of the Syrian Government’s  Use of Chemical Weapons on August 21, 2013": 

U.S. Government Assessment of the Syrian Government’s
Use of Chemical Weapons on August 21, 2013

The United States Government assesses with high confidence that the Syrian government carried out a chemical weapons attack in the Damascus suburbs on August 21, 2013. We further assess that the regime used a nerve agent in the attack. These all-source assessments are based on human, signals, and geospatial intelligence as well as a significant body of open source reporting. Our classified assessments have been shared with the U.S. Congress and key international partners. To protect sources and methods, we cannot publicly release all available intelligence – but what follows is an unclassified summary of the U.S. Intelligence Community’s analysis of what took place.

Syrian Government Use of Chemical Weapons on August 21

A large body of independent sources indicates that a chemical weapons attack took place in the Damascus suburbs on August 21. In addition to U.S. intelligence information, there are accounts from international and Syrian medical personnel; videos; witness accounts; thousands of social media reports from at least 12 different locations in the Damascus area; journalist accounts; and reports from highly credible nongovernmental organizations.

A preliminary U.S. government assessment determined that 1,429 people were killed in the chemical weapons attack, including at least 426 children, though this assessment will certainly evolve as we obtain more information.

We assess with high confidence that the Syrian government carried out the chemical weapons attack against opposition elements in the Damascus suburbs on August 21. We assess that the scenario in which the opposition executed the attack on August 21 is highly unlikely. The body of information used to make this assessment includes intelligence pertaining to the regime’s preparations for this attack and its means of delivery, multiple streams of intelligence about the attack itself and its effect, our post-attack observations, and the differences between the capabilities of the regime and the opposition. Our high confidence assessment is the strongest position that the U.S. Intelligence Community can take short of confirmation. We will continue to seek additional information to close gaps in our understanding of what took place.

Background:

The Syrian regime maintains a stockpile of numerous chemical agents, including mustard, sarin, and VX and has thousands of munitions that can be used to deliver chemical warfare agents.

Syrian President Bashar al-Asad is the ultimate decision maker for the chemical weapons program and members of the program are carefully vetted to ensure security and loyalty. The Syrian Scientific Studies and Research Center (SSRC) – which is subordinate to the Syrian Ministry of Defense – manages Syria’s chemical weapons program.

We assess with high confidence that the Syrian regime has used chemical weapons on a small scale against the opposition multiple times in the last year, including in the Damascus suburbs. This assessment is based on multiple streams of information including reporting of Syrian officials planning and executing chemical weapons attacks and laboratory analysis of physiological samples obtained from a number of individuals, which revealed exposure to sarin. We assess that the opposition has not used chemical weapons.

The Syrian regime has the types of munitions that we assess were used to carry out the attack on August 21, and has the ability to strike simultaneously in multiple locations. We have seen no indication that the opposition has carried out a large-scale, coordinated rocket and artillery attack like the one that occurred on August 21.

We assess that the Syrian regime has used chemical weapons over the last year primarily to gain the upper hand or break a stalemate in areas where it has struggled to seize and hold strategically valuable territory. In this regard, we continue to judge that the Syrian regime views chemical weapons as one of many tools in its arsenal, including air power and ballistic missiles, which they indiscriminately use against the opposition.
