Iraqi authorities say gunmen have raided the home of a Kurdish policeman in the northern city of Kirkuk, killing his wife and three children.
Officials say the attackers entered the policeman's home while he was away early Sunday, and shot his wife and children as they slept.
In other violence in Kirkuk, militants set off two roadside bombs targeting Iraqi security patrols on Sunday, wounding at least three policemen.
Sectarian tension is high in Kirkuk, an oil-rich city that Kurds want to merge with their autonomous region in northern Iraq. Many Arab and Turkmen residents oppose such a move and want to remain under the control of Iraq's central government.
