Seven people, including an Iraqi police chief, were killed and 13 injured Wednesday in a series of attacks targeting security forces in Iraq, DPA reported.
Mohamed Ibrahim, the chief of police investigations for the north- eastern district of Jalawlaa, and three of his companions were killed by a bomb targeting Ibrahim's convoy.
The attack took place on the road linking Jalawlaa, which is located north-east of the city of Baquba, with the al-Saadiya district, security sources said.
On the outskirts of the northern city of Mosul, meanwhile, two soldiers were killed and nine people - most of them civilians - injured by a bomb targeting an Iraqi military patrol.
In a separate attack in Mosul, gunmen also killed a policewoman and injured her brother, security sources said.
In central Fallujah, another three people - including two soldiers - were injured by another bomb targeting an Iraqi military patrol. The city is located some 60 kilometres west of Baghdad.
Attacks on security forces have recently increased in Iraq, as a seven-month political stalemate surrounding the formation of a new government has dragged on.
