Scientists say tear gas was source of Aleppo deaths

British scientists analyzing video from the recent alleged chemical weapons attack in Syria recently reported that they believe the weapon used was an extremely potent type of tear gas and not a never agent

Video of the attack in the northern province of Aleppo, which left 30 people dead and injured an additional 80 people, showed that the victims were exposed to a "super-strength tear gas," scientists at the Porton Down military research institute said, according to the Times of Israel.

The video also shows that victims were suffering from respiratory failure but did not show evidence of burns or lung damage that would be indicative of a nerve agent attack.

In addition to the video, British spies have collected samples of the soil from the scene on which to perform additional analysis.

New Israeli Intelligence Minister Yuval Steinitz, however, alleges that chemical weapons were used, while the Associated Press reports that an unnamed U.S. official doubts the presence of such weapons, according to the Times of Israel.

The U.S. will not rule out the possibility that a chemical weapon was used, but the official said that the U.S., as a result of intelligence gathering, strongly believes that the attack did not involve a weaponized chemical.

Both the Syrian government and opposition forces are blaming each other for the attack.
