BAGHDAD, June 12 (UPI) -- Two government and two police convoys were bombed Thursday in Baghdad, killing at least three Iraqis, an Iraqi Interior Ministry official said.
The three who died were killed in an attack on a police convoy in central Baghdad, CNN reported. At least 15 others were injured.
Another 20 other people were wounded when insurgents targeted separate convoys of a senior Interior Ministry official near Beirut Square, a district mayor in the Shaab neighborhood and police commandos near Sadr City, officials said.
In northern Iraq, U.S. and Iraqi forces killed four suspected terrorists and destroyed an al-Qaida in Iraq hiding place Thursday during a raid, CNN reported.
During the operation near Baquba in Iraq's Diyala province, U.S. military officials said troops destroyed a facility where weapons were stored.
Coalition forces also discovered a "tunnel system, fighting positions, weapons, military-style assault vests and documents detailing terrorist operations," a military spokesman said.
The raid was targeting a suicide bombing network.
