The death toll from a Syrian government raid on an Islamic State of Iraq and Syria (ISIS) stronghold in eastern Syria has risen to 18, including an American fighter with the militant group, activists said Thursday.



The Syrian Observatory for Human Rights said Wednesday’s strike destroyed a building being used as a headquarters and a prison by IS militants in Deir Ezzor province.



The strike on the village of Ghareebeh killed "at least 18 jihadist fighters and leaders, most of them non-Syrians and including an American," the Britain-based Observatory said.



On Wednesday, the Observatory reported that at least five ISIS militants had been killed in that attack, and that the raid enabled some of the jail's prisoners to escape.



ISIS fighters control most of the oil-rich province of Deir Ezzor since routing government troops in July.
