Guerrillas fired mortars at the headquarters of the Patriotic Union of Kurdistan (PUK) in the Iraqi city of Mosul today, killing a passer-by and wounding three PUK guards and a civilian.
Major Dara al-Surchi, chief of the local police station, said four mortar rounds had been fired. One of them landed in the street outside the PUK headquarters and killing an Iraqi.
Mosul, is an ethnically mixed city - Sunni Arabs make up the largest group in the city but there is also a significant Kurdish population.
The PUK is one of the two main Kurdish parties in Iraq. Both parties backed the US-led invasion of Iraq and are represented on Iraq's US-appointed Governing Council.
Guerrillas in Iraq frequently target Iraqis seen as cooperating with the occupation. Ethnic tensions between Arabs, Kurds and Turkmens have also sporadically boiled over into bloodshed in recent months.
