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.
