Amvid shows purported chlorine gas attack in Syria

Chaos on the streets of Syria, where new amateur video appears to show a chlorine gas attack.

Residents of a village in the Hama province can be seen running from a green-yellow gas in the street.

Reuters cannot independently verify the video, which was posted on a social media website.

The video later shows a crowded emergency room where dozens of residents are struggling to breathe.

Opposition activists have blamed President Bashar al-Assad for the attack.

Damascus denies responsibility, instead blaming rebels.

Chlorine is thousands of times less lethal than sarin, which was used in a deadly attack outside Damascus last year.

But the use of chlorine as a weapon is still illegal.
