BAGHDAD, Iraq (CNN) -- Sunni lawmakers walked out of Iraq's parliament Saturday, protesting what they called the house arrest of a prominent Sunni politician.
Iraqi parliament member Adnan al-Dulaimi reportedly is confined to his home.
Troops reportedly went to the house of parliamentarian and Sunni bloc leader Adnan al-Dulaimi, two days after Iraqi and coalition troops found a car bomb outside his office compound, a member of parliament told CNN.
"The Iraqi government said that the security forces are there to protect al-Dulaimi's house, but now the Iraqi army is saying that al-Dulaimi is under house arrest," said Nada Mohammed Ibrahim, a member of parliament and the Sunni secular bloc, Iraqi National Dialogue Front.
Ibrahim said security forces were banning al-Dulaimi and daughter Asmaa Adnan al-Dulaimi from leaving their house.
"This could happen to any ... member in the future, and this is not right," Ibrahim said.
There was no immediate response from the Iraqi or U.S. military.
Ibrahim said members of three Sunni blocs in parliament walked out: Iraqi National Dialogue Front, the secular Sunni bloc called Iraqi List, and al-Dulaimi's main Sunni bloc, National Accord Front.
The U.S. military reported Friday that Iraqi and coalition troops found the car bomb outside al-Dulaimi's western Baghdad office compound on Thursday, during an operation that was spurred by the report of the killing of a "concerned local citizen." "Concerned local citizens" are volunteers who assist troops with security tasks, such as operating checkpoints.
Troops destroyed the car bomb in a "controlled detonation," but five coalition soldiers and an Iraqi civilian were wounded.
More than 40 people were detained in the Thursday operation, the U.S. military said, including al-Dulaimi's son, an official with the Iraqi National Accord Front said Saturday.
Meanwhile, al Qaeda in Iraq insurgents killed at least 10 people and wounded 10 others in a Diyala province village Saturday morning, a Baquba police official said.
The official said residents of Adwaila -- home to both Sunni and Shiite Iraqis -- have opposed al Qaeda, making their town a target for attack.
The insurgents launched mortars into the area and then sent in dozens of fighters with small arms to storm the village, the official said. At least five houses were burned, he said.
Adwaila is about 25 miles northeast of the provincial capital Baquba, which lies 35 miles north of Baghdad.
In other violence, car bombs killed two people and wounded 10 Saturday in and around Baghdad, Iraq, an Interior Ministry official said.
One of the bombs exploded in southeastern Baghdad, killing a civilian and wounding four others, the official said. The bomb detonated in the Moasker al-Rashid area of the Iraqi capital around 9 a.m.
The other car bomb exploded around 11 a.m. in Madaen, killing a civilian and wounding six, the official said. Madaen is a town about 15 miles southeast of Baghdad. E-mail to a friend
