At least 22 people have been killed and others injured in a car bomb targeting a police academy in Babil district in Hilla, south of Baghdad. Hussain al-Haidari, an Iraqi journalist, told Aljazeera a booby-trapped Daewoo car exploded on Wednesday during a graduation ceremony at the police academy. Babil district police spokesman Hadi Hatif said the bomber drove into the compound and came under fire from police before his car exploded. He said at least four cars and three nearby buildings were hit by the blast. The attack came a day after a truck bomb attack on a police commando headquarters in Baghdad killed at least 11 people. Hilla is about 100km south of the capital. Al-Haidari said Hilla is usually calmer than other areas in Babil district such as Latifiya and Iskandariya, where clashes with US and Iraqi forces regularly take place. Fighters have been mounting near-daily attacks on Iraqi security forces in many parts of the country ahead of the planned 30 January elections. **Shiite Iraqis Found Dead in Field Near Mosul*** The bodies of 18 young Iraqis executed after seeking work at a U.S. base have been found in a field near the volatile city of Mosul, police said Thursday. Police in Baghdad said the attackers shot the men, aged between 14 and 20, on Dec. 8 after stopping their two mini-buses about 30 miles west of Mosul as they traveled from Baghdad. Their hands were tied behind their back and each of them was shot in the head. All of them were Shiites from Baghdad's northern neighborhood of Kadhimiya who were hired by an Iraqi contractor to work at a U.S. base in Mosul. **PHOTO CAPTION*** U.S. soldiers and and members of the Iraqi National Guard inspect the scene of a car bomb blast in western Baghdad's district of Amerea, Wednesday, Jan. 5, 2005.
