Life has returned to near normal in Baghdad today after the violent attacks that caused dozens of casualties on Tuesday.According to Voice of Iraq news agency, people began to return to their jobs in Baghdad but traffic has not yet returned to its normal level while security forces have boosted their inspection measures at hundreds of checkpoints both inside and outside the Iraqi capital. The news agency quoting police sources had reported that 80 people were killed and more than 250 injured in the blast.Explosions struck the Shiite neighborhoods of Kadhimiya in the northwest, Amil, Bayaa and Shulaa in the southwest, Ur and Zuhour in the northeast, Sadr City and Amin in the east and Abu Dhsir in the southern part of the city. Other blasts struck mixed Sunni-Shiite neighborhoods, including Yarmouk, Jihad and Eghraiat.AIR correspondent Dhirendra Ojha reports from Dubai that no one has yet announced responsibility for the explosions that hit Iraqi capital yesterday but analyst suspect handiwork of Al Qaida in this incident. A spokesman of the Iraqi Health Ministry told that 70 percent injured have left hospitals after treatment of their minor injuries. Iraqi Prime Minister Noorie al Maliki described the act as highly criminal, which was aimed at destabilizing the government.The series of deadly attacks in Iraq highlighted the serious power vacuum that exists in the country, as it still has no official government. Political parties based on sectarian credential are struggling to form a new government eight months after parliamentary elections. While US forces have ended their combat operation and due to leave Iraq by the end of 2011, most analysts agree that the longer Iraq is without a government, the more unstable the security situation will be.
