The Polish ambassador to Iraq was slightly wounded Wednesday and one civilian was killed in a car bomb attack in downtown Baghdad, according to the Polish Foreign Ministry. Gen. Edward Pietrzyk was taken to a U.S. military hospital, Polish Foreign Ministry spokesman Robert Szaniawski said, adding the ambassador was moving on his own, which meant his injuries were most likely not life-threatening. A civilian passer-by died after the parked car bomb was detonated about 10 a.m., according to an Iraqi police official who spoke on condition of anonymity because he was not authorized to release the information. Four people, including a security guard with the convoy, also were wounded in the attack in the Karradah neighborhood, police said. U.S. Army and Iraqi troops sealed off al-Arasaat street where the attack took place, as U.S. helicopters flew overhead. AP (Associated Press) Television News footage showed the wreckage of at least one mangled car. Pietrzyk, 57, was appointed ambassador to Iraq in April, Szaniawski said.
