LONDON: Commercial ships sailing through the Red Sea are broadcasting increasingly desperate messages on public channels to avoid being attacked by the Houthi militia in Yemen.

One message read “All Crew Muslim,” some included references to an all-Chinese crew and management, others flagged the presence of armed guards on board, and almost all insisted the ships had no connection to Israel.

Maritime security sources said the messages were a sign of growing desperation to avoid attack, but were unlikely to make any difference. Houthi intelligence preparation was “much deeper and forward-leaning,” one source said.

Houthi attacks off Yemen’s coast began in November 2023 in what the group said was in solidarity with Palestinians in the Gaza war. A lull this year ended when they sank two ships last week and killed four crew. Vessels in the fleets of both ships had made calls to Israeli ports in the past year.
