Two mass graves found in Raqa

DAMASCUS: Two mass graves containing dozens of bodies of civilians and Syrian troops killed by Islamic State Jihadists have been found in the west of Raqa province, state news agency Sana reported on Friday.

The bodies were discovered based on information provided by residents near Wawi in the west of the province, which borders Turkey. It said they had been executed.

Recovery operations were expected to last several days "due to the huge area of the two mass graves", Sana quoted a source from the Syrian civil defence as saying.

It was not immediately clear when they had been killed, other than while Islamic State controlled the northerly province, SANA said.

The Islamic State group, which proclaimed a "caliphate" over swathes of Syria and Iraq in 2014, has now lost almost all the land it once controlled.

It has been held responsible for multiple atrocities during its reign of terror, including mass executions and decapitations.
