Libyan militias oust IS from Sirte headquarters

US-backed Libyan militias say they have seized control of the headquarters of so-called Islamic State in Sirte.

“The Ouagadougou [convention] centre is in our hands,” a spokesman for forces loyal to Libya’s UN-backed government of national accord said.

Sirte, on the Mediterranean coast, is IS’s most significant stronghold in Libya.

The city has been under the militant group’s control since February 2015.
