Baghdad - Four people were killed, including two women, and three injured Wednesday in separate attacks in the northern Iraqi city of Mosul, local police said.

"Unknown gunmen stormed into a house in an area of southern Mosul, and killed a man and his wife," a police source said.

In eastern Mosul, gunmen opened fire on a man and his daughter in al-Jazaier district, the source said, adding that three policemen were injured Wednesday when an explosive device went off targeting a police patrol in al-Kokjali area.

Mosul, some 400 kilometres north of Baghdad, is one of the most ethnically and religiously diverse areas in Iraq and remains the site of deadly attacks almost on a daily basis.

On Tuesday, two Iraqi soldiers were injured when insurgents detonated a roadside bomb as their patrol passed on the outskirts of the city.

Police had also found two bodies of men who had apparently been executed in the Mosul district of Hay al-Wahida.

Though the region is predominantly Arab and Sunni Muslim, neighbourhoods of Mosul and villages to the east of the city are home to large Kurdish, Christian, Shabak and Yazidi minorities.(dpa)
