BAGHDAD, Iraq - Three suicide car bombings killed 17 people in northern Iraq on Thursday, including a top municipal council leader and a bodyguard of Iraq's Kurdish deputy prime minister, police said. Continuing violence during the past days has also claimed the lives of three children, a U.S. soldier and a Sunni Muslim cleric, underscoring the rampant, random nature of an insurgency that has killed more than 780 people since the April 28 announcement of Iraq's new Shiite-led government.
