 The attack escalated tensions in Yemen, which has been rocked by weeks of protests against President Ali Abdullah Saleh, a key U.S. ally in the campaign against al-Qaida who has been in power 32 years. Abdullah al-Jeifi, 24, died and several other protesters who were shot in Tuesday's raid were in serious condition, said Mohammed al-Abahi, one of the doctors volunteering at the Sanaa University campus. One of the protest organizers, Rabie Al-Zuraiqi, 23, said he was struck by rubber bullets and gas during the attack. Outraged at the government raid, more protesters camped out in tents near the university and on campus Wednesday. During the past few weeks, 29 people have been killed in the unrest, according to international human rights groups. According to witnesses, the soldiers fired warning shots into the air before shooting gas — and in some cases live bullets — into the crowd, killing one and injuring at least 50. SANAA, Yemen — Doctors from the scene of violent anti-government protests in Yemen’s capital Tuesday night said that what was originally thought to be tear gas fired by government forces on demonstrators might instead have been a form of nerve gas, which is forbidden under international law.
– Doctors and protesters in Yemen think the government is using banned nerve gas, not regular tear gas, to quell protests, reports Global Post. Three doctors treating patients say the symptoms are suspiciously severe. “The material in this gas makes people convulse for hours," said one field doctor after soldiers fired bullets and gas into a crowd of protesters outside Sanaa University yesterday. "We are seeing symptoms in the patient’s nerves, not in their respiratory systems," said another. "I’m 90% sure it's nerve gas and not tear gas." If so, it would put Yemen authorities in violation of international law. Either way, the government seems to be taking an increasingly violent approach, notes Global Post. In addition to the gas, soldiers fired live ammunition, killing one protester. Demonstrations continued today, notes AP.
