On Monday, the Houthis of Yemen claimed that they had used ballistic missiles as well as drones and booby trapped boats to target three vessels in the Red Sea and Mediterranean Sea, including an Oil Tanker.

Yahya Saree, Houthi spokesperson, said that the latest Houthi operations were in response to an Israeli airstrike carried out on Khan Younis, a city located on the southern Gaza Strip, on Saturday. The attack resulted in the deaths of at least 90 Palestinians, and the injuries of 300 more, according to Gaza Health Ministry.

In dozens attacks since November, Houthis have sunk and captured two vessels, killed three sailors, and disrupted global trade, forcing shipowners to avoid popular Suez Canal shortcut.

Recently, it has become more effective in damaging ships. This is largely due to the use of unmanned, armed boats that damage a vulnerable vessel’s waterline.

Saree stated in a televised address that the Houthis had targeted the Chios Lion and Bentley I oil tankers in the Red Sea. U.S. Central Command confirmed the attacks late Monday and stated that no injuries or damage had been reported.

The Houthis claimed that it joined forces with the Iraqi Islamic Resistance to target the Olvia in Mediterranean Sea. Reuters was unable to independently verify the attack.

It was not possible to reach the managers of the Bentley I flying under Panaman flag, Chios Lion flying under Liberian flag and Olvia flying Cyprus Flag for a comment.

On Monday, United Kingdom Maritime Trade Operations reported that two ships were attacked in the Red Sea, off the port of Hodeidah in Yemen. One ship had suffered some damage.

Unmanned drone boats attacked a vessel located 97 nautical mile northwest of Hodeidah. The drones caused some damage to the port side and produced light smoke.

UKMTO and Ambrey, a security firm, separately stated that three small watercraft attacked another merchant vessel 70 nautical miles southwest from Hodeidah.

Three small boats attacked the ship, according to its master. The unmanned watercraft collided twice with the ship while passengers from the other two boats shot at it. UKMTO reported that the vessel took “self-protection” measures and, after 15 minutes, the small craft stopped the attack.

The Master reported that four projectiles had exploded near the vessel in what seemed to be two separate incidents.

Ambrey reported that both the vessel and the crew are safe and have moved on to the next port.

Houthi militants have been attacking shipping lanes along the Red Sea and Gulf of Aden with drones and missiles since November. The group claims that these actions were taken in solidarity with Palestinians who have been affected by Israel’s Gaza war.

Since February, the U.S. and British governments have carried out retaliatory attacks in Yemen, including bombing sites and shooting down drones.

According to a U.S. Defense Intelligence Agency report, Houthi attacks have affected at least 65 countries as well as major energy and shipping firms.
