Govt and rebels trade gas attack accusations

Fighting has intensified around Aleppo

Syrian rebels accused government forces of launching toxic gas attacks on civilians in a town southwest of Aleppo on Tuesday. The government rejected the claim and accused the rebels of using chemical weapons themselves.

Rebel sources provided video of people receiving treatment who they say were among the victims of a gas attack, but the images were not conclusive and neither of the gas attack claims by the rebels or the government could be independently verified.
