A Greek-flagged oil tanker with 25 crew members on board has caught fire after multiple attacks and is adrift in the Red Sea.

There were no reports of injuries to the crew, made up of 23 Filipinos and two Russians. Greece said the ship could have been hit either by missiles or drones.

The Iran-aligned Houthis began to target international shipping near Yemen last November, saying the move was in solidarity with Palestinians over the war in Gaza. The Houthis have not claimed responsibility for the Sounion attack.

Delta Tankers, the ship’s operator, confirmed the ship was adrift and had sustained minor damage. Sounion was on its way from Iraq to a port near Athens where there are many refineries, the Greek port authority said.
