Houthis declare maritime blockade on Saudi Arabia, threatening Bab el-Mandeb oil route; UN warns of wider escalation

Blockade announcement

Yemen's Houthi rebels declared an immediate maritime blockade against Saudi Arabia on Monday, 20 July 2026. Military spokesman Yahya Saree announced the measure in a televised statement, framing it as retaliation for what he called a "continuous Saudi siege" of Houthi-controlled ports and airports. Saree invoked the principle of "an eye for an eye," warning that any Saudi escalation would be met with "a comprehensive and decisive escalation." The blockade, he said, responds to the kingdom's own restrictions on Houthi-held areas and the 13 July attack on Sana airport.

We announce a maritime blockade against the criminal Saudi enemy, based on the equation of 'an eye for an eye,' with immediate effect from the publication of this statement.

Saudi and UN reactions

Saudi Arabia's foreign ministry issued a statement condemning the Houthi declaration in the strongest terms, calling it a "terrorist" act and reiterating support for Yemen's internationally recognised government.

The strongest condemnation of the statements made by the self-proclaimed military spokesman of the terrorist Houthi militia... imposing a maritime blockade on the Kingdom.

At the United Nations, spokesman Stéphane Dujarric expressed deep concern, warning that the threats could trigger "an even greater regional escalation." He called for an immediate de-escalation and respect for freedom of navigation.

We are very concerned about the new threats from the Houthis against Saudi Arabia, against freedom of navigation, which could lead to an even greater regional escalation.

Oil route at risk

The blockade directly threatens the Bab el-Mandeb strait, the southern gateway to the Red Sea and a critical chokepoint for global energy flows. Saudi Arabia relies on this passage to export roughly 3.5 million barrels per day of crude and refined products to Asian markets. A full closure of the strait could reduce global oil supply by an estimated 7%, according to reports. The threat compounds existing disruptions in the Strait of Hormuz, where Iran has imposed restrictions in recent months, potentially pushing total international oil flow losses toward 10%. A closure would force tankers to take the longer route around Africa's Cape of Good Hope, raising shipping costs and delivery times. The Houthis previously disrupted Red Sea shipping during the Gaza war, hijacking vessels and launching drone and missile attacks.

Escalation timeline

The blockade announcement caps a series of military exchanges. On 13 July, Houthi forces launched missiles and drones at Abha International Airport in southern Saudi Arabia, retaliating for a coalition-backed attack on Sana airport. These were the first reciprocal strikes since the UN-brokered ceasefire of 2022. On 14 July, the Houthis claimed to have shot down a Saudi reconnaissance drone. The group controls northwestern Yemen, including the capital Sana, while the Saudi-led coalition maintains control of Yemeni airspace and requires prior authorisation for flights. The Houthis have challenged this by organising direct flights between Iran and Sana, further angering Riyadh.
