The latest assaults on U.S. troops in central Iraq yesterday -- the third in the past week -- occurred as the 1st Armored Division arrived to join the 3rd Infantry Division to double patrols in the Iraqi capital.

Attackers fired rocket-propelled grenades, heavy machine guns and small arms at an eight-vehicle supply convoy in what military officials described as an ambush at 6:15 a.m. near Haditha, 120 miles northwest of Baghdad, killing one soldier from the 3rd Armored Cavalry Regiment and injuring another.

Hours later, one soldier was killed and three wounded when a Humvee near Baghdad International Airport either ran over a land mine or was hit by another type of explosive that had been hurled at it, military officials said
