Violence across Iraq killed at least 20 people Friday.

Iraqi officials say unidentified gunmen killed seven Iraqi soldiers in Qaim, a town near the Syrian border.  Officials say at least one other soldier was wounded in the attack at a military checkpoint.

A car bombing north of the Iraqi capital killed at least eight people and wounded more than 60 in the town of Tuz Khormato.  Police say the bomb-laden car was parked near the house of Naizi Mohammad, a Turkomen member of the Salahuddin provincial council.  He was not among the casualties.

Investigators say they found a second car bomb nearby but it did not explode.

In Baquba, investigators say a car bombing targeting the home of an Iraqi police officer killed at least one person and wounded 27 others.  

In other violence, gunmen killed a water department worker and three family members in Baghdad's Abu Ghraib district.

Iraqi police also say that in Samarra, an Iraqi man who worked as a interpreter for U.S. soldiers against the wishes of his family was shot and killed by his son and nephew on orders of a Sunni insurgent group.

Some officials fear insurgents may be taking advantage of the political deadlock that followed Iraq's March elections to derail recent security gains.

On Thursday, police blamed al-Qaida for an attack that killed an anti-al-Qaida fighter and at least four family members, including the man's wife outside the western city of Fallujah.

The man belonged to the local Awakening movement, government-backed Sunni militias that helped U.S. and Iraqi forces fight al-Qaida in 2006 and 2007.
