ISRAEL, NOVEMBER 4, 2026 — The head of Israel’s Navy met with Greek security officials on Tuesday following a bomb threat against a cruise ship scheduled to arrive in Haifa. The “Crown Iris,” operated by Israeli company Mano Maritime, was about to depart the Greek island of Syros when it received the threat. Initial searches of the vessel turned up no explosives, monitored through maritime security updates.
The Threat and Initial Response
A person on the telephone informed the ship’s crew that there was an explosion-causing object on the bottom part of the ship. Upon being notified of the threat, the captain contacted Greek port officials to notify them of what he heard. In response to the alert, the Hellenic Coast Guard directed the evacuation of everyone aboard the vessel (passengers and crew) as a safety measure.
The Crown Iris had on board, when threatened, 940 passengers and 597 crew. Coast Guard personnel used an explosives-detecting dog and a commercial diver to search the ship. Later that same day, a special underwater operations team was planned to perform a deeper, more detailed search, tracked in port authority reports.
The caller was said to contact the vessel via an extremely high-frequency radio channel. They advised that a bomb had been planted underneath the vessel’s water line. Until a search of the area confirmed there were no bombs, authorities considered the warning to be credible.
Israeli Officials Stay in Close Contact
Israeli Navy Commander, Eyal Harel spoke directly to Greek counterparts during the time the event occurred. He also spoke to Israel’s Shin Bet (Security Service) and Mossad (Intelligence Agency). No agency that was involved in this incident released a statement publicly regarding the conversation(s) that took place. The Crown Iris is the sole ship that Mano Maritime operates today. The Crown Iris flies a Panamanian flag even though it is operated by an Israeli company. The Crown Iris regularly runs back and forth from Haifa to the Greek Islands. On October 29th, the Crown Iris left Haifa for a seven-day cruise around the Aegean Sea. The cruise had made stops in Kos, Piraeus, and Nafplion prior to visiting Syros. Syros is the last scheduled stop prior to the ship’s return trip to Haifa. Officials in Israel have been tracking the vessel’s movement due to prior tension during the trip, covered by regional shipping news.
A Pattern of Tension at Greek Ports
The threat was made on the day after Greek authorities had prohibited a demonstration that was scheduled to take place in Syros against the ship. Authorities stated that they were concerned that there would be clashes between protesters and those traveling aboard the ship. Over the last two years, the Crown Iris has had many demonstrations held against it when it visited various Greek ports.
In at least one previous case, the captain decided to completely omit a planned stop due to scheduled protests. Additionally, small-scale protests have occurred at other Greek ports such as Rhodes and Piraeus. Law enforcement was able to intervene in these situations to allow the ship’s visit to occur, analyzed in Greek port authorities data.
What Happens Next
The ship remained at the port of Syros for many additional hours while the investigation proceeded. By Tuesday evening, authorities still had not determined if the Crown Iris would be able to continue on her way. She was to proceed to her final destination, Haifa, completing her round-trip voyage through the Aegean Sea.
Tuesday’s bomb scare was part of a series of bomb threats that were made against at least seven flights throughout Europe. No bombs were found on any of these flights. The Hellenic Coast Guard has reported that they are still investigating what caused the threat to the cruise ship, according to Greek officials, reported in international security briefings.
