Two Americans, Briton killed in attack on base housing US Terrorists near Baghdad

Citing two unnamed US officials, Reuters reported that based on preliminary information, about a dozen coalition members had also been injured in the Wednesday attack against Iraq's Taji military camp, located some 30 kilometers (18.6 miles) north of Baghdad.

The US-led military coalition in Iraq said in a statement that 18 107mm Katyusha rockets struck the base and suggested they may have been fired from a truck.

It confirmed three troops were killed and about a dozen wounded but declined to disclose the nationalities of the casualties or offer any other identifying information.

"The attack is under investigation by the coalition and Iraqi security forces," the military coalition said.

Earlier, the Iraqi Interior Ministry's Security Media Cell announced in a statement that the incident took place in the evening when 10 rockets landed on Camp Taji, located some 30 kilometers (18.6 miles) north of Baghdad.

The statement added that a Kia Bongo pickup truck with a missile launcher was found south of Baghdad's al-Rashidiya district. It had three missiles in its back.

No group has so far claimed responsibility for the attack, which came less than a week after two Katyusha rockets were fired at the heavily fortified Green Zone in central Baghdad.

An Interior Ministry official said at time that the incident took place on March 5 evening when the projectiles were launched at the zone, which houses the US embassy as well as some of the main Iraqi government offices.

The official added the rockets landed on empty area and caused no casualty. A third rocket landed on a nearby area west of the Green Zone, without causing casualties.

On January 14, Iraq's military announced in a statement that the military camp had been targeted by two Katyusha rockets.

Four Katyusha rockets hit the same base on December 29 last year.
