The U.S.-backed Syrian Democratic Forces clashed with I.S. Fighters in Baghouz Area in Eastern Syria.

SDF has been laying siege to I.S. Militants’ last enclave east of the Euphrates, the Village of Baghouz, for several weeks.

A Spokesman for the U.S.-backed Syrian Force said, some 200 of the Militants surrendered in Baghouz after a ferocious battle at the weekend, but around 1,000 may still be holding out.

While the group’s defeat in Baghouz would mark a milestone in the fight against I.S. Group, the Militants are expected to remain an insurgent threat inside Syria and Iraq.
