Russian ships and submarines are taking part in the search for the Arctic Sea ship, satellites and other search and observation equipment are used in the operation, Itar-Tass quoted Russian Ambassador to Cape Verde Alexander Karpushkin as saying. The Russian diplomat answering questions did not specify to reporters, however, in what area the search is underway. He said that the Cape Verde authorities who told the media that the vessel was 400 miles from the archipelago “did not officially notify the Russian embassy about this.” “I turned to the Cape Verde main armed forces HQ, but they did not confirm this information about the vessel's whereabouts,” he added. Karpushkin also disproved information that Russia requested the Cape Verde authorities to permit its ships engaged in the Arctic Sea search enter the country's territorial waters. “This request had been planned, but we refused from it later. The search will be conducted in other areas,” the ambassador said.
