DUBAI, United Arab Emirates (AP) — Suspected attacks by Yemen's Houthi rebels targeted two ships in the Red Sea on Monday, authorities said, near where crews hope to salvage a tanker loaded with oil and still ablaze after another assault by the group.

The attacks are believed to be the latest in the Iranian-backed rebels’ campaign that has disrupted the $1 trillion in goods that pass through the Red Sea each year over the Israel-Hamas war in the Gaza Strip as well as halted some aid shipments to conflict-ravaged Sudan and Yemen.

Meanwhile, the efforts to salvage the still-burning Sounion seek to head off the potential ecological disaster posed by its cargo of 1 million barrels of crude oil.

In Monday's first assault, two projectiles hit the vessel, and a third explosion occurred near the ship, the British military's United Kingdom Maritime Trade Operations center said.

“Damage control is underway,” the UKMTO said. “There are no casualties onboard and the vessel is proceeding to its next port of call.”

The timing of the attack and coordinates offered by the UKMTO corresponded to the reported path of the Panama-flagged oil tanker Blue Lagoon I, now traveling south through the Red Sea to an unlisted destination. The Blue Lagoon I was coming from Russia's port of Ust-Luga on the Baltic Sea and had been broadcasting that it had Russian-origin cargo on board.

In recent months, the Blue Lagoon I traveled to India, which gets more than 40% of its oil imports from Russia despite Moscow's ongoing war on Ukraine and the international sanctions it faces over it.

The Greek-based firm operating the ship could not be immediately reached.

Later Monday morning, the UKMTO reported a second attack off the Houthi-controlled port city of Hodeida. The private security firm Ambrey said n aerial drone hit a merchant ship, though no damage or injuries were reported. The attack happened only a few kilometers (miles) from where the Blue Lagoon I attack occurred, Ambrey said.

The Houthis did not immediately claim responsibility for the attacks. However, it can take the rebels hours or even days to acknowledge their assaults.

The Houthis have targeted more than 80 vessels with missiles and drones since the war in Gaza started in October. They seized one vessel and sank two in the campaign that also killed four sailors. Other missiles and drones have either been intercepted by a United States-led coalition in the Red Sea or failed to reach their targets.

The rebels maintain that they target ships linked to Israel, the U.S. or the U.K. to force an end to Israel’s campaign against Hamas in Gaza. However, many of the ships attacked have little or no connection to the conflict, including some bound for Iran.

Meanwhile Monday, a salvage effort appeared to be underway to tow away the Sounion oil tanker, which was earlier hit by the Houthis and abandoned by its crew. Jamel Amer, an official with the Houthis, wrote online Saturday that tug boats assigned to pull the Sounion away should arrive Sunday. However, NASA fire satellites showed a blaze at the site of where the Sounion had been abandoned on Monday morning.

The Sounion was carrying some 1 million barrels of oil when the Houthis initially attacked it on Aug. 21 with small arms fire, projectiles and a drone boat. A French destroyer operating as part of the European Union’s Operation Aspides rescued the Sounion’s crew of 25 Filipinos and Russians, as well as four private security personnel, after they abandoned the vessel and took them to nearby Djibouti.

Last week, the Houthis released footage showing they planted explosives on board the Sounion and blew them up in a propaganda video, something the rebels have done before in their campaign.
