They were kidnapped yesterday at about 7 p.m. Moscow time in north-eastern Baghdad, according to the company.
The company reports that a two-storied residential building houses 23 adjusters who are engaged in three facilities for the restoration and reconstruction of a thermal power station near Baghdad. When 15 to 20 gunmen in masks broke into the house, there were 12 men in there. Three of them managed to escape.
The specialists were taken away in a minibus and a car.
One of them was released later.
The Russian embassy in Baghdad is looking into the incident.
"The Russian embassy is doing everything to find out what has happened and have the Russian specialists released," said Alexander Yakovenko, an official Russian foreign ministry spokesman.
"The foreign ministry recommends that Russian residents should not visit Iraq for the time being as the situation has aggravated dramatically there," said Mr Yakovenko.
