A car bomb left at least 14 people dead in the capital on Friday, while U.S. troops killed five al-Qaeda members.
In Baghdad, police claimed to have uncovered a weapons cache on property owned by the son of Adnan al-Dulaimi, one of Iraq's most influential Sunni politicians. His son, Maki Adnan al-Dulaimi, was jailed one month ago for his alleged involvement with some car bombs found at his father's Baghdad compound.
The midday attack in Tayaran Square came just after Friday prayers.
And in Diyala province just north of Baghdad, the U.S. military said it had killed four armed men tied to al-Qaeda in Iraq in an operation near Muqdadiyah in Diyala. Another was killed in a predominantly Sunni area south of Baghdad.
"These operations are examples of our continued success against al-Qaida," said Maj. Winfield Danielson, a spokesman for the U.S.-led Multinational Forces. "Iraqi and coalition forces are disrupting (al-Qaida) operations and diminishing their pool of manpower, but they still pose a threat to innocent Iraqis," he was quoted as saying by the AP.
