KIEV, Dec. 16 - Ukraine accused Russia on Wednesday of looting two of its oil rigs after Crimea-based oil and gas firm Chornomornaftogaz moved the equipment off the coast of the annexed peninsula into Russian waters, Reuters reported.

Russia annexed Crimea from Ukraine last year and the loss of the peninsula's valuable energy assets has been a particular sore point for cash-strapped Kiev given a long-running energy dispute between the two countries.
