About 90 miles off the coast of the Yemeni port city of Hodeida, individuals in numerous small boats opened fire on the Greek-flagged MV Sounion, apparently hitting the ship with at least four projectiles.
According to officials, the attack may have involved the employment of missiles or drones.
The tanker lost power and caught fire as a result of the attack on Wednesday.
A French military warship saved the 25 sailors who were forced to abandon the ship.
After that, the MV Sounion drifted away, but authorities said on Thursday that it had been secured.
Because of the amount of oil on board, a spokesman for the EU’s Aspides military operation in the Red Sea cautioned on Thursday that the tanker presented a “environmental hazard”.
They said that one unmanned drone boat in the area had also been destroyed by its crews.
Officials from the Houthi movement in Yemen have stated that their soldiers attacked both the Sounion and the Panama-flagged ship SW North Wind I, which was slightly damaged in another attack.
Large swaths of the nation are under the group’s control, and since last autumn, they have been attacking vessels in the vicinity to show support for the Palestinian people and to exert pressure on Israel to stop its assault in Gaza.
