Two car bombs targeting US and Iraqi security forces have exploded in different parts of Baghdad, killing three people, police said.
The shock wave from the first blast near the international airport on Tuesday shook nearby buildings and was heard across the southwestern part of the capital.
Police said two civilians were killed in the blast.
Another car bomb exploded in the path of a US military convoy in al-Dura area south of Baghdad, Aljazeera reported.
One civilian was injured and brought to Yarmuk hospital in western Baghdad, a medical source said. Another person was reported to have been killed, but no further details were provided.
A US Humvee and a civilian car were destroyed in the explosion.
US forces cordoned off the area, while Iraqi forces have prevented anyone from approaching it.
US soldiers killed
Meanwhile, one Iraqi soldier and two US soldiers were killed on Monday in an intense battle with fighters northeast of Baghdad, the US military said on Tuesday.
"Coalition forces and Iraqi army soldiers encountered and attacked terrorist forces in a remotely populated region east of Baghdad at about 4pm (1200 GMT) on 4 April," a US military statement said.
A US marine was killed in action on Monday in Iraq's al-Anbar province west of Baghdad, the US military also said.
The marine was killed by "an explosion which occurred during combat operations".
In related news, police sources also said a general in the Iraqi army had been captured.
An Interior Ministry source said Brigadier-General Jalal Muhammad Salih and his bodyguards were pulled from his car by an armed group in the Mansur district of the capital at 11.30am (0730 GMT).
He was the commander in charge of the ministry's 1600-strong armoured brigade.
Bodies found
Meanwhile, Iraqi police found the corpses of 10 Iraqi soldiers buried in the Jurf al-Sakhr area, south of Baghdad, Aljazeera learned.
In Hilla, armed men killed a member of the Babil provincial council, Salim Hilal, as he was heading to work, Babil provincial police spokesman Captain Muthana Khalid said.
He said two suspects in the attack were arrested.
In the central city of Baquba, armed men wounded a government translator and killed her father in a drive-by shooting, said Brigadier General Adil Mulan of the Diala provincial police department.
Prison riot
Meanwhile, the US army issued a statement revealing details of a riot at one of the prisons it runs in southern Iraq.
Inmates at Camp Bucca - the largest US-run prison in Iraq - hurled rocks and set tents on fire earlier this month, and four guards and 12 prisoners were wounded before the riot was brought under control on 1 April.
It said prisoners in one compound protested about the transfer of detainees to another compound.
"During the disturbance, the detainees chanted, threw rocks and set several of their tents on fire," an army statement said.
"The disturbance was brought under control with only minor injuries to four guards and 12 detainees."
Last month, prison guards foiled a jailbreak by finding two tunnels dug under the ground at Camp Bucca. One of the tunnels had cleared the perimeter fence of the prison.
In January, US guards shot and killed four inmates during a riot at the same camp.
