Syria has been accused of using poison gas to attack a rebel-held town, despite agreeing to dismantle its chemical weapons and production facilities earlier this year, reports Reuters. Another group, the Syrian Revolution Coordinators Union, reported nine casualties and also accused the regime of using poison gas. Syria has been under intense pressure to end its chemical weapons program. The United States called chemical weapons a red line and began preparing for a missile strike on Syria after a major attack in August reportedly left hundreds dead.
