Iraqi police say a suicide truck bomber has killed at least 20 people and wounded 27 in a Kurdish village in northern Iraq.

The blast took place early Thursday in Wardak village near the city of Mosul. Police say a second suicide attack was thwarted, when Iraqi security forces opened fire on the bomber before he could trigger the explosives on his truck.

In a separate incident, police say four people were killed and 29 wounded in a bomb attack in Mahmudiya, south of Baghdad.

On Wednesday, a car bomb exploded outside a house in the northern city of Kirkuk, killing eight people and flattening at least one building.

Police said it appeared the car was being rigged for a bomb attack and exploded prematurely in the yard of the house.
