Baghdad ? Insurgents, who have increasingly turned to women to stage suicide bombings, on Tuesday used a man dressed as a woman in a failed assassination attempt on a provincial governor, the U.S. military and witnesses said.

The target, Gov. Raad Tamimi of Diyala province, escaped unharmed. But at least one other person was killed and several were wounded when the bomber’s vest exploded near the governor’s convoy.

The use of the man in disguise appeared designed to give the attacker easier access to his target.

It was the second suicide bomb attack in two days in Baqubah, the capital of Diyala. On Monday, a 15-year-old girl blew herself up, killing one Iraqi police officer.

Witnesses said the bomber Tuesday was foiled by Iraqi soldiers stationed along the route. U.S. Army Maj. Margaret Kageleiry said the soldiers shot at the bomber, which caused him to detonate his vest prematurely.
