MOSCOW — A Russian icebreaker carrying over 100 tourists, scientists and journalists on a cruise around Antarctica was struggling to free itself from sea ice but was not in any danger, a shipping company said Tuesday. The Captain Khlebnikov icebreaker is about 5 miles from clear water near Snow Hill Island in the Weddell Sea, German Kuzin of the Fareastern Shipping Company told Russia’s Vesti 24 television. He said neither the ship nor the passengers faced any risks.
