The Houthis have made several claims that the Yemen-based militant group has targeted ships in the Mediterranean — but without evidence that a strike has taken place.

Maritime security experts have described the claimed attacks not as a true geographical expansion of the militant group’s assault on shipping, but rather as an escalation of its information war.

Ian Ralby, a US-based maritime law and security expert who is chief executive of IR Consilium, said there have been layers and phases of the Houthis’ operations since the war between Israel and Gaza began in October.
