At least 23 people have been killed, including children, in airstrikes on two Syrian towns on the outskirts of Damascus, activists say.
The strikes targeted the towns of Qusair and Kfar Batna in the province of Homs, a deadly evening after a suspected chemical attack in Idlib province.
Thirty-eight people, including 13 children, died in a suspected gas attack on a rebel-held town in the northern province of Idlib.
Syria’s opposition has accused the regime of using poisonous gas.
The Syrian Observatory for Human Rights monitoring group says those killed in the airstrikes on Qusair include eight women and six children.
Both the authorities and a Russian military organisation providing support for President Bashar al-Assad are known to operate in the area.
A rebel group also carried out the air strikes, activists in Qusair say.
Warplanes also struck Kfar Batna, in the northern countryside of Homs, leaving at least eight people dead and 15 wounded, according to the Local Coordination Committees.
The Syrian government has said it is investigating the claim that gas was used in Idlib on Wednesday.
The BBC’s Haroon Siddique, reporting from Syria, says the government has not revealed whether it believes the attack was carried out by its own forces.
Air strikes have frequently hit opposition-held areas, while air raids have injured thousands.
The strikes on Thursday evening in Kfar Batna struck a mosque and a number of homes, including those of a father and his children.
Activists said the incident came hours after warplanes pounded the town.
The Syrian Observatory for Human Rights says there have been several reports of chlorine gas attacks in the province of Idlib since January.
Senior Syrian opposition member Issam al Rayes has accused the Syrian government of being behind them.
The Observatory has said 40 people died in that attack on 25 March.
The government has not commented on that attack.
Bashar al-Assad’s government has denied using chemical weapons.
