Greece warns Greek ships to avoid key waterways due to Iran's retaliatory strikes following U.S.-Israel attacks.

On February 28, 2026, Greece advised Greek-flagged ships to avoid the Persian Gulf, Gulf of Oman, and Strait of Hormuz due to heightened security risks following U.S.-Israel strikes on Iran. The warning cited threats including missile and drone attacks, port strikes, and electronic interference, with concerns over potential conflict escalation into the Red Sea and Gulf of Aden. Iran responded with retaliatory strikes, including closing the Strait of Hormuz, disrupting shipping, and targeting U.S. and Israeli sites. The situation remains volatile, with global energy markets and regional stability at risk.
