DUBAI – Yemen’s Houthi rebels continued an hourslong attack Tuesday targeting a Liberian-flagged cargo ship in the Red Sea, authorities said, after the group claimed to have sunk another vessel in an assault that threatens to renew combat across the vital waterway.

The Greek-owned Eternity C remains “surrounded by small craft and is under continuous attack,” the United Kingdom Maritime Trade Operations center warned Tuesday. At least two people on board the ship were reported to be hurt and two others missing.

The bulk carrier had been heading north toward the Suez Canal when it came under fire by men in small boats and by bomb-carrying drones Monday night. The security guards on board also fired their weapons. The European Union anti-piracy patrol Operation Atalanta and the private security firm Ambrey both reported those details.

While the Houthis haven’t claimed the attack, Yemen’s exiled government and the EU force blamed the rebels for the attack.

The Houthis separately attacked the Liberian-flagged, Greek-owned bulk carrier Magic Seas on Sunday with drones, missiles, rocket-propelled grenades and small arms fire, forcing its crew of 22 to abandon the vessel. The rebels later said it sank in the Red Sea.

The two attacks and a round of Israeli airstrikes early Monday targeting the rebels raised fears of a renewed Houthi campaign against shipping that could again draw in U.S. and Western forces, particularly after U.S. President Donald Trump’s administration targeted the rebels in a major airstrike campaign.

The attacks come at a sensitive moment in the Middle East, as a possible ceasefire in the Israel-Hamas war hangs in the balance, and as Iran weighs whether to restart negotiations over its nuclear program following American airstrikes targeting its most sensitive atomic sites during the Israel-Iran war in June.

The Houthi rebels have been launching missile and drone attacks against commercial and military ships in the region in what the group’s leadership has described as an effort to end Israel’s offensive against Hamas in the Gaza Strip.

Between November 2023 and January 2025, the Houthis targeted more than 100 merchant vessels with missiles and drones, sinking two of them and killing four sailors. Their campaign has greatly reduced the flow of trade through the Red Sea corridor, which typically sees $1 trillion of goods move through it annually. Shipping through the Red Sea, while still lower than normal, has increased in recent weeks.

The Houthis paused attacks until the U.S. launched a broad assault against the rebels in mid-March. That ended weeks later and the Houthis hadn’t attacked a vessel until this weekend, though they did continue occasional missile attacks targeting Israel.
