Iran continues to defy international pressure to stop its nuclear program.
The Islamic Republic announced it test-fired a surface-to-surface cruise missile in international waters near the strait of Hormuz on Monday. The launch came during a 10-day exercise designed to be a show of force by the Iranian Navy.
The missile, called Ghader, or Capable in Farsi, was described as an upgraded version of a missile that has been used before. The official IRNA news agency said the missile "successfully hit its intended target" during the exercise.
One-sixth of the world's oil supply passes through the strait.
Iran has threatened to shut down the oil passage if Washington imposes additional sanctions targeting the country's crude exports.
"The Strait of Hormuz is completely under our control," Iran's navy chief Adm. Habibollah Sayyari said after Monday's test. "We do not allow any enemy to pose threats to our interests."
Iranian state TV said two more missiles, with a shorter range, were also tested Monday.
