MOSCOW, January 11 (RIA Novosti) - Russian railroad monopoly RZD and diamond miner Alrosa closed a deal to fully acquire the embattled KIT Finance group, KIT Finance said Sunday.

"Now the group is controlled by KIT Finance Holding Company whose ultimate owners are RZD and Alrosa," the statement said.

Alrosa and RZD, the Russian acronym for Russian Railways, each owns 45% in the holding company through their subsidiaries, and 10% is owned by National Capital.

Russia's antitrust service approved in November an application by Alrosa to buy a 45% stake in KIT Finance Holding Co. The Antimonopoly Service had earlier given Russian Railways the go-ahead to buy 45% in the struggling company via the rail monopoly's 100% subsidiary, KRP-Invest.
