At least six people, including three children were killed late Monday in an alleged chlorine bomb attack carried out by Bashar al-Assad’s regime on the northern Syrian province of Idlib, a Syrian opposition coalition said.

According to the Syrian Revolution General Commission’s statement released Tuesday, the regime airstrikes targeted opposition-controlled villages of Sermin and Qminas villages.

Hospitals in the area were reportedly overwhelmed with dozens of people suffering from chlorine gas.

“A family of six people, including three children chocked to death because of the toxic chlorine gas used in Syrian regime airstrikes on Sermin village Monday evening,” the commission said.

The coalition described the attack as “massacre” and feared the death toll may rise because of lack of adequate medical aid in the area.

Also, a video published on social networks supposedly showed victims of the attack and scores of people receiving first aid at hospitals.

The attack follows UN Security Council's recently adopted resolution on March 6, which condemned the use of chlorine attacks in Syria.
