Gun and bomb attacks killed three policemen and a soldier and wounded six other people in Iraq on Monday, security and medical officials said.
Police Lieutenant Colonel Saad al-Hamdani said gunmen opened fire with light weapons on a checkpoint in the Hamam al-Alil area, 35 kilometres (21 miles) from the restive northern city of Mosul, then fled the scene.
The attack killed three policemen and wounded two others, Hamdani said.
Gunmen also shot dead a soldier in Baquba, in central Iraq's Diyala province, a police colonel and a medical source at a local hospital said.
A roadside bomb against a police patrol wounded three police in Khales, 65 kilometres (40 miles) north of Baghdad, a police major and a medical source said.
And gunmen wounded a police first lieutenant in the Karrada area of central Baghdad, an interior ministry official said.
Violence in Iraq has declined dramatically since its peak in 2006-2007, but attacks remain common, especially in Baghdad, Diyala and Mosul. A total of 132 Iraqis were killed in violence in May, official figures show.
