Sporadic clashes are reportedly continuing at a university campus in the Iraqi city of Ramadi stormed by Al-Qaeda-linked militants two days ago.
A security source told RFE/RL that militants were still holding at least 15 of Anbar University staff hostage.
Militants from the Islamic State of Iraq and the Levant (ISIL), an Al-Qaeda splinter group, attacked the university campus in Ramadi, the capital of Anbar Province, on June 7.
Fierce clashes were also reported in the city of Fallujah and the nearby town of Garma, also in Anbar Province.
ISIL and other Sunni-led militants have controlled parts of Anbar province, including the city of Fallujah and parts of Ramadi, since late December.
