TEHRAN - The Iranian parliament's national security and foreign policy committee has approved the general outlines of a strategic action plan to "ensure the security and sustainable progress" of the Strait of Hormuz and the Gulf, the official news agency IRNA reported Sunday.

The plan was discussed at a committee meeting and approved without opposition, IRNA quoted committee spokesperson Hassan Qashqavi as saying.

Qashqavi said lawmakers reviewed submissions from relevant Iranian bodies before endorsing the plan's general framework.

The legislation was formally introduced to the parliament on July 13, according to IRNA.

Iran tightened its grip on the strait on Feb 28, barring safe passage of vessels belonging to or affiliated with Israel and the United States following their joint strikes on Iranian territory.
