U.S. troops in Fallujah, Iraq, have captured two former Iraqi army generals suspected of spearheading anti-coalition fighting, coalition officials said Wednesday.

Troops from the 505th Parachute Infantry Regiment of the 82nd Airborne Division captured the generals in a raid Tuesday not far from where 15 soldiers died in a helicopter crash Sunday.

The former generals are suspected of being key financiers and organizers of anti-coalition fighters operating around Fallujah, coalition officials said.

Afterward, troops from the 16th Infantry Regiment, attached to the division, found an array of ammunition, including 225 rounds of 60 mm mortar ammunition, 20 rocket-propelled grenades and 100 rounds of .50-caliber machine gun ammunition, officials said.

Elsewhere, soldiers from Task Force Ironhorse, led by the 4th Infantry Division, found a cache of explosives, weapons, ammunition and a grenade launcher in a raid on a building in Hadid thought to be a safe house for people suspected of mortar attacks.
