A major Russian contractor in Iraq is considering withdrawing after one of the company's workers was killed and two were kidnapped in another day of violence.
The three were employees of the engineering firm Interenergoservis working at the Southern Baghdad power station.
State television reported the workers had been travelling between Baghdad and Latifiya on Monday evening when their car was attacked by unknown assailants.
Eight of the company's workers were kidnapped in Baghdad last month.
Elsewhere, four people were killed and 23 hurt when a bomb exploded in a northern oil town town of Kirkuk. The bomb went off in a mostly Kurdish district of the city.
There are also reports of an attack on a civilian supply convoy on the road between Baghdad and Jordan today. US officials say a number of people are missing.
Elsewhere, the body of a westerner, believed to be American, has been found in Baghdad. US officials said the man whose body was found on Monday, was not a member of the U armed forces and did not work for the Defence Department.
