A report on the official Iranian news agency says Iran is planning naval maneuvers in international waters near strategic Strait of Hormuz, where one-fifth of world oil supply passes.

The IRNA new agency quotes Iran's navy chief, Adm. Habibollah Sayyari, as saying the maneuvers will begin Friday from Strait of Hormuz to the northern part of Indian Ocean in an area of about 1 million square kilometers (400,000 square miles).

Iran threatened to close the strait over Western sanctions aimed at its suspect nuclear program but has not repeated the threat lately.

Adm. Sayyari said Tuesday Iran will fire missiles and deploy vessels and submarines during the six-day war games.

Iran holds military exercises to test and upgrade its military equipment as well as to boost its regional military standing.
