U.S. defense officials say that the U.S. has seized two tanker ships.

One of them is a stateless motor tanker called the Sophia. The other is a Russian-flagged oil tanker originally called the Bella-1, and U.S. defense officials say that tanker has links to Venezuela.

U.S. forces have chased it across the Atlantic for weeks. The U.S. Coast Guard first tried to board the vessel last month, but it refused to be boarded. The tanker had reached the North Atlantic Ocean, between Iceland and Britain, before it was seized. Officials believe it may have been headed to a Russian port in the Arctic when it was boarded.
