The Houthi rebels in Yemen have announced a significant escalation in their campaign against Israel, vowing to target any ship associated with Israeli ports or companies, regardless of the vessel's nationality. This move comes as the group cites worsening humanitarian conditions in Gaza as the reason for their actions. The Houthis have warned all companies to cease dealings with Israeli ports immediately, threatening attacks wherever possible. Recent incidents include an assault on a Greek-owned cargo ship in the Red Sea, highlighting the ongoing risks to international shipping in the region.
