The Houthis recently declared a naval blockade on Saudi Arabia in the Red Sea, targeting several tankers.

Yemen’s Iran-aligned Houthi group says it has fired ballistic missiles at a Saudi oil tanker, more than a week after imposing a naval blockade on Saudi vessels in the Red Sea.

In a post on X, Yahya Saree, the Houthi military spokesman, said the group had “carried out a military operation targeting the Saudi oil tanker (NCC GHAZAL) for violating the maritime navigation ban” that the group had imposed on Saudi vessels.

He added that the group had used several ballistic missiles and forced the vessel to retreat.

The UK Maritime Trade Operations (UKMTO), a maritime security monitor, said a tanker reported an explosion while transiting the Red Sea, adding that the crew is safe and no environmental damage was reported.

The Houthis seized the capital Sanaa in 2014 and have fought the internationally recognised Yemeni government, which Saudi Arabia backs, for more than a decade.

On July 20, the Houthis announced their maritime blockade, accusing Saudi leaders of imposing “an unjust and oppressive siege” on Yemen for nearly 12 years, “plundering our resources and imposing a comprehensive blockade”.

It went on to affirm “the right of our great people to respond to the blockade with a blockade”.

Second attack

The Houthis have also claimed an attack on two Saudi oil tankers transiting the Red Sea last week.

“We targeted two Saudi oil tankers, named Encelia and Layla, for their violation of the blockade decision issued by the armed forces,” Houthi military spokesperson Yahya Saree said on July 22.

The Saudi Press Agency reported that the Encelia had been hit, citing an official source at Saudi Arabia’s Transport General Authority who said all crew members were safe.

The Bab al-Mandeb chokepoint connecting the Red Sea to the Gulf of Aden is one of the world’s most important shipping routes, including for oil exports.

Between Yemen to the northeast and Djibouti and Eritrea in the Horn of Africa to the southwest, the strait is just 29km (18 miles) at its narrowest point, limiting traffic to two channels for inbound and outbound vessels heading to the Suez Canal.

In 2024, about 4.1 billion barrels of crude oil and refined petroleum products passed through the strait – about 5 percent of the global total.
