Mosul, Iraq - An Iraqi policeman was killed and three civilians were wounded when a suicide bomber targeted the home of the governor of a northern Iraqi province, Baghdad's Buratha news agency reported Monday.

Citing local police, it said a man detonated explosives packed into his car 150 metres away from the home of Athil al-Najifi, governor of Iraq's northern Nineveh province, in downtown Mosul, some 400 kilometres north of Baghdad. The governor was apparently unharmed.

Nineveh, which is among the most ethnically and religiously diverse areas of Iraq, has been the site of near-daily deadly attacks in recent months, despite successive security pushes that police say have netted hundreds of suspected militants.

Late on Sunday night, police told the German Press Agency dpa that militants had fatally shot a police officer in downtown Mosul.

In a separate incident on Sunday evening, "unknown gunmen" fatally shot a civil servant in the Hay al-Zuhur district of eastern Mosul. A bystander was also injured in that incident, police said.

Also on Sunday evening, a car bomb targeting an Iraqi military patrol east of Mosul injured two Iraqi soldiers and four civilians bystanders, police told dpa.

That attack followed an attack on an Iraqi police patrol in the western Mosul district of Den-Den, police said. Four people, including one policeman, were killed in that car-bomb attack.

Police in eastern Mosul also said they had found five unidentified bodies in the Tahrir neighbourhood earlier that day.
