Jihadists took staff and students hostage on Saturday at a university campus in the Iraqi city of Ramadi, where security forces have battled anti-government fighters for months, police said. The attack is the third major operation by militants in three days, following heavy fighting and suicide bombings in **rthern Iraq on Friday and a major assault on the city of Samarra on Thursday. The militants from the Islamic State of Iraq and the Levant group infiltrated the university from the nearby Al-Tasha area, killed its guards, and blew up the bridge leading to its main gate, police said. An AFP journalist said that security forces have cordoned off the campus.
