Yemen’s Houthi movement claimed on Tuesday that it carried out another attack on an oil tanker in the northern Red Sea, adding to a series of maritime incidents that have raised concern over shipping routes near one of the world’s key trade corridors.

Houthi spokesperson Yahya Saree said in a social media post that the Saudi tanker Wafa was targeted off the coast of Yanbu with several ballistic missiles.

The claim came one day after the Indian-flagged vessel MSV Faize Noore Oliya sank off the coast of Yemen on Tuesday. India’s Ministry of External Affairs said on Tuesday that all 13 Indian crew members were rescued.

Saree said the group has targeted eight tankers since imposing a maritime blockade on Saudi Arabia on July 22. He also said at least 29 Saudi ships have either been prevented from passing through the Red Sea or forced to turn back.

The stated focus on tankers underscores why these claims are being watched beyond the immediate parties involved: the Red Sea is a major route for regional energy shipments and commercial traffic, so repeated attack claims draw close attention from shipping operators and governments tracking the safety of passage.

“The Yemeni Armed Forces affirm that their operations will continue and escalate in targeting Saudi oil tankers in the northern Red Sea to close all access points and prevent their passage, thus establishing a blockade-for-blockade equation,” Saree said.
