A ship traveling through the Red Sea on Thursday reported being hit in an attack likely carried out by Yemen’s Houthi rebels, a private security firm said, the latest in the campaign targeting shipping over the Israel-Hamas war.

The ship issued a radio call off the coast of the rebel-held port city of Hodeida, saying it had been struck, the private security firm Ambrey said.

A warship in the area was responding to the attack, Ambrey added. It wasn’t clear if anyone was hurt or if the ship was damaged in the assault on the vessel. Neither the British nor US militaries immediately reported the attack.

The Houthis did not immediately claim the attack. However, it can take hours or even days for them to acknowledge their assaults. The rebels have targeted more than 60 vessels by firing missiles and drones in their campaign that has killed a total of four sailors. They seized one vessel and sunk two since November. A US-led airstrike campaign has targeted the Houthis since January, with a series of strikes on May 30 killing at least 16 people and wounding 42 others, the rebels say. The Houthis maintain that their attacks target ships linked to Israel, the United States or Britain. However, many of the ships attacked have little or no connection to the Israel-Hamas war — including those bound for Iran.

Late on Tuesday, Houthi military spokesman Brig Gen Yahya Saree claimed an attack Monday on the Liberian-flagged, Greek-managed container ship MSC Sarah V. Late on Wednesday, the Houthis claimed that they used a new hypersonic ballistic missile in the assault, which targeted a ship farther away than nearly all of the previous assaults they’ve launched in the Gulf of Aden.

The US military’s Central Command also said it destroyed a Houthi radar site. Another attack Wednesday in the Gulf of Aden was suspected to have been carried out by the Houthis, though they have yet to claim it.
