London (AP) — Britain's government says the legal conditions have been clearly met for taking action against Syria for allegedly launching a chemical attack against its people.

Prime Minister David Cameron's office released two documents Thursday meant to bolster the case that chemical weapons were used by Syria. In addition to the legal summary, Downing Street released the Joint Intelligence Committee assessment that concludes it was "highly likely" that the regime was responsible for the chemical weapons attacks in a Damascus suburb on Aug. 21.

The committee says there was no credible intelligence to suggest the attack was faked by opposition forces.

The documents were released ahead of a parliamentary debate on Syria. The opposition Labour Party has indicated it may not support even a watered down version of a resolution on Syria.
