A senior Iranian naval commander says his country has sent several warships to the Atlantic Ocean, close to U.S. maritime borders for the first time.

The commander of Iran’s Northern Navy Fleet, Admiral Afshin Rezayee Haddad, is quoted by the official IRNA news agency as saying Saturday that the vessels have already begun the journey to the Atlantic Ocean via waters near South Africa.

“Iran’s military fleet is approaching the United States’ maritime borders, and this move has a message,” Haddad reportedly said, according to Fars, a semi-official Iranian news agency.
