Forty Qaeda leaders killed or caught in Iraq: U.S.

Good news from Iraq keeps coming.

BAGHDAD (Reuters) - Forty senior al Qaeda in Iraq members were either captured or killed in November, including a senior adviser to the Sunni Islamist group's leader, the U.S. military said on Tuesday.

Violence levels in Iraq have fallen to their lowest levels since January 2006 after a security crackdown, which included a deployment of an extra 30,000 U.S. troops, targeting al Qaeda and Shi'ite militias across the country.
