The main U.S-backed Syrian force fighting the Islamic State group says a Russian airstrike on a gas field it recently captured from the extremists killed one of its fighters.

A statement issued by the Syrian Democratic Forces said two other fighters were wounded in Monday's strike in the eastern province of Deir el-Zour.

It says the attack occurred on the Conoco gas field, which the SDF captured from IS on Saturday.

On Sept. 16, the SDF said a Russian airstrike wounded six of its fighters, but Moscow denied carrying out the attack. Russian officials did not immediately respond to a request for comment on the latest allegation.

Syrian state media say two people have been killed in shelling on President Bashar Assad's ancestral village of Qardaha.

Syria's state broadcaster said Monday the village has been shelled by "terrorists" for two days straight. It says two people were wounded Sunday.

Qardaha is located in the coastal mountains of northwest Syria. Assad's father, the late president Hafez Assad, was born in Qardaha. He was buried there in 2000.

The village has been largely spared from the violence of Syria's civil war, which grew out of demonstrations in 2011 against the Assad family's four-decade rule.

The Britain-based Syrian Observatory for Human Rights also reported the shelling, saying two civilians have been killed.
