In attacks in Samarra, about 100 km (60 miles) north of Baghdad, security sources said multiple gunmen wearing suicide vests took over two police stations, killing at least seven policemen, according to Kareem Raheem and Ghazwan Hassan of Reuters.
The mayor of Samarra, Mahmoud Khalaf, said security forces had regained control, killing at least six assailants, but declined to comment on the number of casualties on the government side.
The pro-Islamic State news agency Amaq said the militants had executed some policemen. The upsurge in violence comes as U.S-backed Iraqi forces try to drive Islamic State from the northern city of Mosul, where the militants are putting up fierce resistance.
