BEIRUT, Nov 9 (Reuters) - At least 20 members of the Syrian security forces were killed and several wounded when fighters from rebel battalions attacked the headquarters of a military security building in northern Syria, a watchdog said.
The attack happened in Ras al-Ain, an Arab and Kurd town in the northeastern province of Hasaka, the opposition-linked Syrian Observatory for Human Rights said, quoting witnesses and a doctor. Rebels overran the frontier town late on Thursday.
"The fate of more than 25 policemen remains unknown," the statement said. (Reporting by Oliver Holmes; Editing by Janet Lawrence)
