WORLD BRIEFING / IRAQ

A suicide bomber drove a truck through a sandbag barrier at a checkpoint to strike a police station in the northern Iraqi city of Mosul, killing at least eight people and wounding 12, U.S. and Iraqi officials said.

The bomber broke through the first checkpoint on the station’s perimeter, then detonated his explosives when he reached a concrete wall a few yards from the building, police said.

No one had claimed responsibility for the attack.
