Iran briefly closes parts of Strait of Hormuz during IRGC drill

2026-02-17 · shipping · major

Iran said parts of the Strait of Hormuz were shut to traffic for several hours on Tuesday February 17 during the IRGC Navy's live-fire 'Smart Control of the Strait of Hormuz' exercise, which began February 16, with IRGC Navy commander Alireza Tangsiri saying his force was ready to close the strait if ordered - a demonstration of Iran's ability to disrupt the waterway. The partial closure coincided with the second round of US-Iran nuclear talks in Geneva the same day.
