Iraqi authorities say a suicide bomber killed four policemen in Baghdad and gunmen killed at least 11 other Iraqis in another town Thursday.
Police say the gunmen killed the 11 men and women in Latifiyah. They believe the victims were members of an extended Shi'ite family.
To the north, in Baghdad, the suicide bomber blew himself up outside Iraq's Interior Ministry. In a separate attack in the capital, a roadside bomb killed a U.S. soldier.
U.S. Brigadier General Donald Alston said Thursday that U.S. forces expected insurgent attacks to increase after security measures imposed for Iraq's elections were lifted.
Meanwhile, al-Qaida in Iraq posted video footage on the Internet it says shows five Sudanese nationals, including a diplomat, abducted in Baghdad. The group threatened to kill the five unless Sudan cuts ties with Iraq.
