Thought to be members of the Al Sheitaat tribe which had battled ISIL militants
More than 230 bodies of people believed killed by ISIL

The bodies were thought to be members of the Al Sheitaat

In August, activists said the militant group had
killed some 700 members of the Sheitaat tribe, the majority of them civilians,
over the preceding two weeks after conflict flared when the militants took over
The people in the newly-discovered mass grave are
believed to have been killed around the same time, activists said.
The Observatory, which has tracked violence on all
sides of the nearly four-year-old conflict, said many of the Sheitaat victims
had been beheaded.
The tribe is from Deir Al Zor province and numbers
