Baghdad hit by deadly car bomb

A car bomb blew up in Baghdad, killing a civilian and wounding four others, an Interior Ministry official said.

The Sunday attack underscored the fragility of relative calm in the Iraqi capital; violence levels have dropped sharply in Baghdad and across the country over the past few months.

Early Sunday in northern Iraq, U.S. forces killed two relatives of Salaheddin's governor Hamad al-Qaisi and identified them as members of al Qaeda in Iraq.

But a Baiji police official who is al-Qaisi's brother said the two males were al-Qaisi's 16-year-old son and the teenager's cousin. Lt. Col. Saad al-Qaisi said the two were "executed," as they headed to morning prayers.

Al-Qaisi said his nephew, Hussam Hamad al-Qaisi, and Badri Khalaf Issa walked out of a house next door to the building that was being raided by the U.S. military at around 3:30 a.m. He said the young men "were taken and executed" by the military.

Baiji is located north of Baghdad in Salaheddin province.
