At least two missiles hit the Iraqi capital city of Baghdad at 8:14 a.m. (0514 GMT) Saturday, injuring two people including an Egypt and a Kuwaiti, the Xinhua correspondent reported.
The missile attack came less than two hours after the previous bombardment by the US-led coalition forces.
As the war entered its 10th day, the city believed to be the major battleground between the Iraqi and coalition forces already witnessed very powerful explosions at 6:35 a.m. local time (0335 GMT).
Fire and smoke were seen in different parts of Baghdad. At one point, huge mushroom-like smoke was observed rising into the sky.
At midnight, a building in the main presidential palace in central Baghdad was hit.
Al Jazeera TV reported early Saturday that the Iraqi Information Ministry in central Baghdad was hit during a bombing attack. Iraqi forces launched anti-aircraft batteries on coalition warplanes.
Witnesses said they heard at least three big blasts followed by another five coming from the US forces.
Earlier in the day, at least 53 people were killed and 47 others injured in coalition's bombings on a market in Baghdad. Baghdad has been under devastating bombings over the past nine days since the outbreak of the war.
On Friday night, explosions also rocked the southern outskirts of Baghdad during the new wave of US air strike on the Iraqi capital. Iraqi Information Minister Mohammed Said al-Sahaf strongly accused the US-led coalition of using cluster bombs on Iraqi civilians. He said a total of 26 Iraqis were killed and 60 others injured during the overnight bombings on the central city of Najaf, and seven were killed and 92 others injured overnight in Baghdad.
Some 116 people have been killed and 695 injured in the southern city of Basra since the beginning of the war, he said, adding in the southern province of Thi Qar, 230 people have been killed and 800 injured.
