U.S.: Iraqi ringleader dead

BAGHDAD, May 21 (UPI) -- An explosion in western Baghdad killed three Iraqi soldiers and injured two others Monday.

The bomb exploded near the home of Adnan Al-Dulaimi, the Iraqi police commander in Al-Adel province, police sources told the Kuwait News Agency, KUNA.

Also Monday, an Iraqi court sentenced 37 terrorists, including eight linked to the al-Qaida terror network, to life in prison, KUNA reported.

Meanwhile, the leader of an Iraqi insurgent group that killed five U.S. soldiers in a January attack in Karbala has been killed by American troops, a military spokesman said.

U.S. Army Maj. Gen. William Caldwell told CNN Sheik Azhar al-Dulaymi was killed Friday in Baghdad.

"We've been pursuing this guy relentlessly," Caldwell told CNN. "Anybody who kidnaps an American soldier and murders them we're going to continue to hunt down."

In the Jan. 20 attack, insurgents "disguised as American soldiers, driving American vehicles, speaking English" attacked a military compound in Karbala, killing one U.S. soldier and kidnapping four others, who were killed later, Caldwell said.
