( dpa ) - At least four Iraqis were killed Monday, including a leader of the Iraqi Shiite Sadrist movement, and other six were wounded, while 63 suspects of al-Qaeda terrorist group were detained. Fayad al-Mosawy, a senior Sadrist figure in the southern city of Basra, was killed by militants in the early hours of the morning, Hareth al-Azary of the Sadr movement told Deutsche Presse-Agentur dpa. "Killing al-Mosawy is a horrible crime that apparently targets the Sadr movement," said al-Azary. The Sadrists are loyal to radical Shiite cleric Moqtada al-Sadr. Also on Monday, an Iraqi judge was killed in a separate attack in southern Baghdad. No further details were immediately available. In a separate incident, two Iraqi soldiers were killed in the southern Baghdad suburb of Zafarania, the Iraqi news agency Voices of Iraq (VOI) said. The soldiers were shot by militants on the way back to the weekend at their homes. In other news, six Iraqis, including civilians and policemen, were injured when an explosive vehicle was detonated near the headquarters of the Iraqi Islamic Party in the northern Iraqi city of Mosul, VOI said. Iraqi security forces have found four unidentified corpses in the Iraqi province of Anbar, some 110 kilometres west of Baghdad. Sources said the corpses were moved to hospital for identification. In Diyala province, 60 kilometres north of Baghdad, a dozen of suspects of al-Qaeda terrorist network were killed and 63 were arrested during the second phase of the joint US-Iraqi military operation given the code name "Operation Iron Harvest." The operation was launched last Tuesday targeting al-Qaeda militants in the Iraqi province. Earlier this week, at least 20 militant suspects have been killed and 10 were detained during this operation. In the late hours of Saturday, Iraqi forces killed a number of militants who were trying to detonate an explosive device in the city of Mosul.
