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.

Iranian officials said last month that the fleet consisted of a destroyer and a logistic helicopter carrier, which will be on a three-month mission.

Haddad says the fleet is approaching U.S. maritime borders for the first time. The Islamic Republic considers the move as a response to U.S. naval deployments near its own coastlines. The U.S. Navy's 5th fleet is based in nearby Bahrain.
