"Witnesses present at the scene of Tuesday’s anti-government protests in the capital Sana’a said that what was originally thought to be tear gas may have been some form of nerve gas, reports said on Wednesday.
Military personnel used live bullets and some form of gas on Tuesday night to disperse a group of demonstrators who were trying to bring more tents into the protest area outside Sana’a University.
One protester was killed and around 100 others were injured in the attack. "
