BAGHDAD (Agencies) At least 57 people were killed and nearly 250 wounded in coordinated car bombings in Shia districts across Baghdad on Tuesday, an Interior Ministry official said. Fifty-seven people were killed and 248 were wounded in 11 car bombings. All of the explosions happened at the same time, the official said. With details of the carnage still unfolding, the latest figures contrasted with an earlier report by the health minister that 36 people had died and 320 been hurt. Explosions struck the Shia neighbourhoods of Kadhimiyah in the northwest; Amil, Bayaa and Shulaa in the southwest; Ur and Zuhour in the northeast; Sadr City, Kamaliya and Amin in the east; and Abu Dhsir in the southern part of the city. Other blasts struck mixed Sunni-Shia neighbourhoods, including Waziriya, Yarmouk, Jihad and Eghraiat. The biggest were in the eastern Husseiniyah and northern Kadhimiyah districts. The attacks came just two days after Al-Qaeda gunmen stormed a church in the heart of the capital and took dozens of worshippers hostage, with 58 of them killed and 60 wounded in a drama that ended with a raid by Iraqi special forces. An interior ministry official said that all of the bombs targeted Shia districts of the capital, and some had exploded near cafes or restaurants. In a separate incident, four mortar rounds struck the mixed Shia and Sunni district of Ghazaliyah earlier in the day, but there was no immediate report of possible casualties. The Interior Ministry announced an immediate curfew in eastern Baghdad, closing off the attacked districts from the rest of the capital. There was already a regular curfew in effect across the capital from midnight to 5:00 am. Iraq has been without a government since inconclusive March 7 elections, in which the Shiite-led State of Law bloc of Prime Minister Nuri al-Maliki finished a narrow second behind Iyad Allawis Sunni-dominated Iraqiya group. Both have been locked in back-room negotiations with different political blocs, but neither has been able to muster the majority needed to form a government. The car bombings and the attack on Christians are a blow to the countrys efforts to attract foreign investment and technology to rebuild the war-wrecked country. Eleven cars exploded with bombs inside them. There were also four roadside bombs and two sticky bombs, Baghdad security spokesman Maj-Gene Qassim Al-Moussawi said. (They were) all in Shia neighbourhoods. (They were) all in Shia neighbourhoods.
