MOSCOW, June 4 - Gazprom says Ukraine owes it $7 billion for failing to take contracted gas minimums in 2012, but the Russian gas giant has not said whether it will seek redress in arbitration.

"The contract specifies volumes, shortfalls in take-up. Under the contract we have the right to compensation for shortfalls in gas take-up. We are acting in accordance with the contract," Alexander Medvedev, a deputy CEO of Gazprom and the head of Gazprom Export, said at a press conference.
