Al-Masirah TV (the main TV news outlet of Yemen's Houthi Movement) reported on Monday that U.S.-led forces had carried out six airstrikes at Hodeidah International Airport, and four on Kamaran Island, near the port city of Salif, off the Red Sea.

The U.S. led coalition has not targeted Kamaran since the airstrikes against Houthi targets started in early February.

These missile attacks follow on from the Houthis, backed by Iran, first successful armed maritime strike and other rocket assaults which damaged the Tutor & Verbena cargo vessels last week. Military and security experts say that both vessels have been abandoned and are adrift, with Tutor in danger of sinking.

Since November, the Houthis who control Yemen's capital, and its most populous regions, have launched attacks on international shipping in Red Sea in solidarity with Palestinians living in Gaza. They have destroyed one ship, taken another vessel, and killed three sailors.

Yemen's internationally-recognised government believes Houthi fighters in the past have used Kamaran Island and Port Salif as a site to launch their Red Sea attacks as well as hide stockpiles of missiles and drones in its salt mines, two military sources within the government told Reuters.

Ships must also transit the 10-kilometer stretch of water between the port of Salif and Kamaran Island to reach their next port.

Officials from the military and security services said that the Liberian flagged Tutor is absorbing water after the Houthis attacked it on Wednesday with an armed drone boat and air missiles in the Red Sea. The attack caused flooding in the engine room of the Tutor.

The crew of the Tutor has been airlifted to safety by rescuers from Dwight D. Eisenhower Carrier Strike Group, an aircraft carrier in the United States. One sailor is still missing.

The U.S. Central Command said separately that crewmembers of the Palau flagged Verbena sent a distress signal this weekend because of uncontrolled fires caused by two Houthi rocket strikes on the Gulf of Aden last Thursday.

CENTCOM reported that the wheat carrier Anna-Meta, flying under the Cayman Islands flag, rescued Verbena’s crew. It is now transporting them safely.

The Houthis, despite retaliation from the U.S. British coalition and other navies have intensified their campaign against commercial ships in one of the busiest shipping routes on the planet.

The missile and drone attacks forced ship owners into rerouting vessels away from the crucial Suez Canal shortcut, causing costs and delays to cascade through the ocean shipping industry which transports around 80% of the international trade.
