Houthi rebels have released footage of attacks on two cargo ships travelling through the Red Sea - a critical waterway for the world's oil and commodities. The Iran-backed militant group used missiles and drones to sink a Liberian-flagged bulk carrier, killing four of the 24 crew, according to a European Union naval force. Earlier, a Greek-owned vessel was also targeted and sunk, with all the crew rescued. A Houthi spokesperson said the attacks were in solidarity with the Palestinians in Gaza. T
