Commercial ships still sailing through the Red Sea are broadcasting messages about their nationality and even religion on their public tracking systems to avoid being targeted by Yemen’s Iran-backed Houthis after deadly attacks this week by the rebels.
The Red Sea is a critical waterway for oil and commodities but traffic has dropped sharply since Houthi attacks off Yemen’s coast began in November 2023 in what the Iran-aligned group said was in solidarity with Palestinians in the Gaza war.
The group sank two ships this week after months of calm and its leader Abdul Malik al-Houthi reiterated there would be no passage for any company transporting goods connected to Israel.
In recent days more ships sailing through the southern Red Sea and the narrow Bab al-Mandab strait have added messages to their AIS public tracking profiles that can be seen when clicking on a vessel.
Messages have included referring to an all-Chinese crew and management, and flagging the presence of armed guards on board.
“All Crew Muslim,” read one message, while others made clear the ships had no connection to Israel, according to MarineTraffic and LSEG ship-tracking AIS data.
Maritime security sources said this was a sign of growing desperation to avoid attack by Houthi commandos or deadly drones — but they also thought it was unlikely to make any difference.
Houthi intelligence preparation was “much deeper and forward-leaning”, one source said.
Vessels in the broader fleets of both ships attacked and sunk by the Houthis this week had made calls to Israeli ports in the past year, shipping analysis showed.
Maritime security sources said even though shipping companies must step up due diligence on any tangential link to Israel before sailing through the Red Sea, the risk of attack was still high.
