Argentina said today five British companies were illegally exploring for oil off the Falklands, Bloomberg reported.
The activities of Rockhopper Exploration, Desire Petroleum Public Limited Company, Argos Resources, Falkland Oil and Gas Limited and Borders & Southern Petroleum were “illegal and clandestine” and cleared the way for legal action, the government said, according to the Buenos Aires Herald.
The companies "are not authorized by the Argentine government under law," Agence France-Presse reported, citing a resolution published in Argentina's Official Bulletin by Energy Secretary Daniel Cameron.
