BEIRUT - Syrian opposition activists have posted photographs and video that they say shows an improvised chlorine bomb to back up claims that President Bashar Assad's forces used chemical weapons in two attacks last week.
Rebels and the government have blamed each other for the alleged poison gas attacks on Friday and Saturday on rebel-held Kfar Zeita village in the central province of Hama, 125 miles(201 km) north of Damascus.
Both sides said chlorine gas - a deadly agent widely used in World War I - had been used. The gas, which has industrial uses, is not on a list of chemical weapons that Assad declared to the global chemical weapons watchdog last year for destruction.
It is a so-called dual-use chemical, which would have to be declared to the Organisation for the Prohibition of Chemical Weapons (OPCW), a spokesman said.
