Kurdish-led forces said they raided part of a prison seized by Islamic State fighters in northeastern Syria and forced at least 300 of the militants to surrender on Monday.
The Syrian Democratic Forces (SDF), spearheaded by the Kurdish YPG militia, said militants were still holed up in other buildings, and plans were underway to clear the rest of the detention complex in Hasaka city.
"The operations to break into the prison have begun," one SDF source said. Another said allies in a U.S.-led coalition were involved in the "ongoing operations" without elaborating. There was no immediate statement from Islamic State.
