US, Iraqi forces kill 250 militants

US and Iraqi forces killed 250 gunmen in a fierce battle involving US tanks and helicopters on the outskirts of the Shi'ite holy city of Najaf yesterday, a senior Iraqi police officer said.

The day-long battle was continuing after nightfall, Colonel Ali Nomas said, as tens of thousands of pilgrims converged on the nearby city of Kerbala for the climax of the Ashura commemorations. A US helicopter was shot down in the fighting, Iraq security sources said. The US military declined comment. A Reuters reporter saw a helicopter come down trailing smoke.

Shi'ite political sources said the gunmen appeared to be both Sunni Arabs and Shi'ites loyal to a cleric called Ahmed Hassani.

In Baghdad, 13 people were killed in bombings in mainly Shi'ite areas, police said.

Twin car bombs targeting ethnic Kurds killed 16 people as night fell in the northern oil city of Kirkuk, whose population is a volatile mix of Kurds, Turkmen and Sunni and Shi'ite Arabs.

Hundreds of thousands of pilgrims have converged on Iraq's other main Shi'ite holy city, Kerbala, for Ashura, marking the 7th century Battle of Kerbala, which helped consolidate the schism between Shi'ite and Sunni Islam. It ends today.

It is the first time the 10-day annual ritual has been held since violence erupted last February between Iraq's majority Shi'ites and once-dominant minority Sunnis. Tens of thousands have since been killed in tit-for-tat killings.

The governor of Najaf province said Iraqi troops fought a day-long battle with up to 200 Sunni gunmen, including foreign fighters, holed up in orchards on the northern outskirts of the city, seat of Iraq's most powerful Shi'ite clerics.
