Suspected Houthi attack targets ship in Gulf of Aden

A suspected attack by Yemen's Houthi rebels targeted a ship in the Gulf of Aden on Tuesday, the latest assault by the group on the crucial maritime trade route.

The captain of the ship reported an explosion in close proximity to the vessel off the coast of Nishtun, Yemen, close to the country's border with Oman, the British military's United Kingdom Maritime Trade Operations center said. The ship, whose name and flag were not released, and all crew are safe, the UKMTO said in a warning to mariners.

The explosion took place in the farthest reaches of the waterway earlier targeted by the rebels, the center said.

It did not elaborate on what caused the explosion, though the Houthis have been known to use drones and missiles as well as bomb-carrying drone boats.

The Houthis did not immediately comment. However, it can take hours or even days before they acknowledge carrying out an attack. The last reported Houthi attack in the region took place June 28.

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 sank two since November. U.S.-led airstrikes have 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 as part of rebel support for the militant group Hamas in its war against Israel in the Gaza Strip. However, many of the ships attacked have little or no connection to the Israel-Hamas war — including some bound for Iran.
