Four people were killed and two others wounded in two attacks in the Iraqi northern province of Kirkuk, a local police source said Saturday.
A roadside bomb went off late Friday near an Iraqi army patrol in al-Rashad area, some 20 km south of Kirkuk city, the capital of Kirkuk province, killing two soldiers and wounding two others, the source told Xinhua on condition of anonymity.
Early on Saturday, gunmen broke into a house of a policeman in al-Musallah neighborhood in northern the city of Kirkuk, some 250 km north of Baghdad, killing the policeman and his brother, the source said.
The two victims were stabbed to death by sharp weapons, the source added.
The ethnically mix city of Kirkuk has been the scene of three massive bomb attacks on Thursday that claimed the lives of 29 people, most of them policemen.
The oil-rich Kirkuk province is part of the disputed areas between the Kurds and both Arabs and Turkomans. The province has long been the hotbed of insurgency since the U.S.-led invasion in 2003.
