The Houthis are attempting to push into the Kahboub Mountains after seizing much of Yemen’s Red Sea coast in a lightning offensive this month – an advance that experts say could dramatically shift the balance of power in the country’s war if successful.

The renewed fighting in recent months with forces aligned with Yemen’s Saudi-backed, internationally recognised government has brought an end to the relative calm that had largely held since 2022. In recent days, the conflict has moved into the rugged highlands overlooking the approaches to Bab al-Mandeb, one of the world’s most important shipping routes.

The strait connects the Indian Ocean to the Red Sea and the Suez Canal, and its importance is only growing as shipping through the Strait of Hormuz remains disrupted by the Houthis’ main ally: Iran.

Experts said taking the high ground would help the Houthis defend the newly captured coastline and make it far harder for government forces to push them back. While the mountains may not necessarily be used as a launchpad for attacks on ships, controlling them would provide defensive depth and cover for Houthi positions closer to the coast, making missile and drone operations in the Red Sea easier to sustain and harder to disrupt.

The Houthis have said they do not intend to target United States shipping and attacks would be limited to vessels linked to Saudi Arabia. But the group has repeatedly attacked ships in the Red Sea in previous years, including vessels with no clear connection to its stated targets.

The Houthi advance has taken on added urgency after The New York Times reported that US President Donald Trump came close to ordering air attacks against the Houthis on Sunday, only to call them off at the last minute. Britain, meanwhile, said it will support Saudi Arabia with defensive refuelling.

Why is Kahboub strategically important?

Kahboub, a mountainous region spanning parts of the Lahj and Taiz governorates in southern Yemen, derives much of its strategic importance from its proximity to Bab al-Mandeb. Some of its heights lie about 40km (25 miles) from the waterway, providing commanding views across a stretch of the Red Sea, through which a significant share of global maritime trade and millions of barrels of oil pass each day.

While that vantage point has considerable military value, experts said the mountains are unlikely to serve directly as a launchpad for attacks in the Red Sea. Their more immediate importance for the Houthis lies in securing the territory the group has already captured.

“The mountains are the natural wall that protects the Houthis’ rear on the coast. Controlling them would cut the coast off from the government-held south and place direct pressure on Lahj and, in the longer term, Aden,” Faozi Al-Goidi, a visiting fellow at the Middle East Council on Global Affairs, told Al Jazeera.

Securing their rear would help the Houthis prevent government forces from attacking their coastal positions from behind or severing the routes connecting their newly captured territory. Until the high ground is secured, Houthi forces stationed along the Red Sea remain vulnerable to attacks from government-held areas to the south and east.

Capturing the elevated positions, therefore, would make Kahboub less important as a potential launchpad for maritime attacks than as a defensive shield for the Houthis’ military gains along the coast.

Ewa K Strzelecka, a visiting senior fellow at the London School of Economics, told Al Jazeera that controlling the coastline, Mayyun Island and the neighbouring highlands would give the Houthis “strategic resilience”.

“Holding the coastline, Mayyun and the adjacent highlands together would give the Houthis a much deeper and more defensible position around one of the world’s principal maritime chokepoints,” she said.

Those positions would allow the Houthis to move fighters, weapons and supplies along the coast with less risk of their routes being severed from behind.

“From the high ground, the Houthis could monitor movements along the coast, around Mayyun Island and towards the chokepoint while protecting missile, drone and potentially unmanned-boat infrastructure positioned farther inland,” Andreas Krieg, a senior lecturer at the School of Security Studies at King’s College London, told Al Jazeera.

The battle is already proving slower than the Houthis’ rapid advance across the coastal plains. Footage circulated on X by the Taiz Military Axis Command’s media centre appears to show intense fighting between forces aligned with the Yemeni government, local fighters and the Houthis on mountain fronts. The footage could not be independently verified by Al Jazeera.

“This is not an easy battle,” said Mohammed al-Basha, an analyst and a former spokesperson for Yemen’s embassy in Washington. “The fighting is taking place across some of Yemen’s most unforgiving terrain where control of a single hilltop or mountain peak can come at a heavy cost.”

Could the Houthis isolate Taiz by controlling Kahboub?

Control of Kahboub could also place greater pressure on Taiz, a symbolically and strategically important city, as the Taiz governorate forms a bridge between the Houthi-held north and the government-held south and the Red Sea coast. Whoever controls it gains the upper hand in the movement of weapons and supplies between the interior and the southern port city of Aden. Losing it, therefore, could deal a serious blow to the government.

Murad Al-Arefi, an editor at the Sana’a Center, told Al Jazeera that taking Kahboub would “increase pressure on the southern and western approaches to Taiz” although he cautioned that it should not yet be seen as evidence of a broader attempt to encircle the city.

The immediate threat to the Taiz-Aden connection is less direct because Kahboub does not itself sit across the route.  “What matters is whether the Houthis can subsequently push farther east through Al-Wazi’iyah and towards the Al-Turbah-Lahj axis, which would place much greater pressure on the southern approaches to Taiz and potentially weaken its connection with Aden,” Strzelecka said.

A further advance, therefore, could leave government forces defending several mountain fronts simultaneously while relying on fewer secure routes to move troops, weapons and supplies, leaving Taiz increasingly exposed. One of Yemen’s largest population centres, Taiz became an important centre of resistance to the Houthis after they seized Sanaa in 2014, and was besieged by the rebel group for years. A major Houthi breakthrough there, therefore, would carry symbolic significance far beyond the territory captured.

What could it mean for Red Sea shipping?

Officially, the Houthis have said their current restrictions in Bab al-Mandeb would apply only to Saudi-linked shipping.

But during its previous Red Sea campaign, the group struck or endangered ships with no clear connection to Israel – their purported target during Israel’s genocidal war on Gaza – raising questions about how narrowly any new restrictions would be applied. Seizing the Kahboub Mountains would further strengthen the Houthis’ position by helping them secure the coastline overlooking Bab al-Mandeb and making it harder for their opponents to push them back.

Simon Mabon, a professor of international relations at Lancaster University, told Al Jazeera that the offensive showed the Houthis using their momentum to capture more territory, weaken their opponents and “dominate Yemen further”.

“This is the Houthis trying to seize more ground and diminish the capacity of their enemies while increasing their strategic ability to close Bab al-Mandeb,” Mabon said.

Intensifying attacks between Saudi Arabia and Yemen’s Houthis have reportedly killed at least five people in total, including three children.

At least one person – a Yemeni resident in Saudi Arabia – was killed, and two others were injured after a Houthi drone was intercepted in Saudi Arabia’s southwestern governorate of Taif on Thursday, according to the kingdom’s civil defence agency.

It is the first death announced in Saudi Arabia this month since Yemen’s Iran-allied Houthis intensified their attacks.

In Yemen on Thursday, the Houthis said “Saudi enemy warplanes targeted three telecommunications towers” in Taiz province.

One civilian was killed in Taiz and another injured in strikes on the town of Abs, Yemen, said Houthi-linked Almasirah television.

Houthi-backed media later reported that “three children were killed and several Yemeni nationals were injured in strikes by the Saudi-backed mercenaries”, a reference to the country’s internationally recognised government forces.

Houthis reject claim they attacked Mecca

The escalation comes as Saudi Arabia said a drone was launched by the Houthis towards Mecca before being intercepted and destroyed.

“It’s a heinous lie,” Houthi leader Abdel-Malik al-Houthi said in a live televised address on Thursday, calling Saudi claims that his group would target Islam’s holiest city “a great propaganda”.

“The sanctity of Mecca is particularly important to the people of Yemen,” he said while accusing Saudi Arabia of “weaponising lies” to serve its war objectives against the Houthis.

Reporting from the Yemeni capital Sanaa, Al Jazeera’s Yousef Mawry said: “Al-Houthi’s speech is not just directed towards the Yemeni people; it is directed to the world to set the record straight that the Houthis did not target the holy city of Mecca, as the Saudis claim.”

In his address, al-Houthi also said Saudi Arabia had initiated the latest round of conflict in Yemen and that Houthi forces are acting defensively.

Meanwhile, Rashad al-Alimi, the head of Yemen’s Saudi-backed Presidential Leadership Council, said that Houthi forces are suffering heavy blows on the fronts in Taiz, Marib, Lahj, al-Jawf, Hajjah, al-Bayda al-Dhale.

In a meeting with the French ambassador to Yemen, al-Alimi said that gains made by the Houthis along the Red Sea coast are temporary, the state-run Saba news agency reported.

Aggression against Mecca ‘a condemned act’

Esmaeil Baghaei, Iran’s Ministry of Foreign Affairs spokesperson, said in a statement on X on Thursday that any aggression against Islamic holy sites, particularly Mecca, “is a condemned act”.

But he added that “a mere claim” of intercepting a drone “en route to Mecca” is not enough to accuse the Houthis of the act.

“Nor should we forget that our region has witnessed numerous instances of ‘false flag’ operations, particularly in recent months,” Baghaei said while pointing at Israel.

Meanwhile, China ⁠has privately asked Iranian officials to help rein in the ⁠Houthis after Saudi Arabia appealed to Beijing following recent Houthi attacks, anonymous sources in Iran told the Reuters news agency.

Beijing publicly called for restraint, dialogue and the restoration of safe navigation, but its private message went further than that, Reuters reported.

The escalation is also threatening to draw in other regional actors – specifically Saudi defence partners Pakistan and Turkiye, which signed a joint defence agreement with the kingdom last month.

Pakistan’s Defence Minister Khawaja Asif said the time has come to implement the Mecca agreement with Saudi Arabia and Turkiye due to recent Houthi attacks.

Asif’s comments to Pakistani media on Thursday were made as Iran’s Foreign Minister Abbas Araghchi said he’d held a phone conversation with Pakistan’s army chief Asim Munir to discuss “regional developments”.

Fighting is continuing along Yemen’s western front, with government forces reporting strikes against Houthi positions in areas stretching from Taiz toward the Red Sea coast.

The government said on Monday that its forces targeted Houthi personnel, equipment and positions in Dhu Bab in Taiz governorate and Khokha in neighboring Hodeidah governorate.

The areas are strategically important because they lie along Yemen’s western coastline near the Red Sea and Bab Al-Mandab Strait, one of the world’s key maritime chokepoints connecting the Red Sea with the Gulf of Aden and wider Indian Ocean.

Dhu Bab is close to Bab Al-Mandab, while Khokha lies further north along the Red Sea coast. The fighting is taking place along territory that links the front lines around Taiz with Yemen’s strategically important western coastline.

Yemen’s armed forces spokesman, Col. Majid Al-Nazili, said government forces targeted Houthi equipment, personnel and positions in the two areas.

Military commanders also visited several front lines around Taiz, including areas near Bani Omar, Jardad and Al-Wazi’iyah, to assess combat readiness.

Maj. Gen. Abu Bakr Al-Jubouli, commander of the Tor Al-Baha axis, said government forces had inflicted heavy losses on the Houthis during recent clashes.

Tehran, Iran – Iranian authorities and state media have praised the Houthis’ capture of Yemen’s Red Sea coast, which some see as giving Tehran more leverage against the United States.

The Houthis, a political and armed group dominated by Zaidi Shia Muslims, have been fighting against the Western-backed Yemeni government since capturing the capital, Sanaa, in 2014.

The Houthis captured a series of Red Sea coastal cities and islands this week, essentially giving them control over the vital Bab al-Mandeb strait.

The Iran-allied group’s recent victories have been praised in Iran, and are viewed by some as part of Tehran’s wider war against the US, ongoing since February 28.

“The victories of Yemen’s Ansar Allah in the western coast is a narrative of a divine triumph and the fruit of years of steadfastness in the most difficult of battlefields,” Hossein Mohebbi, spokesman of the Islamic Revolutionary Guard Corps (IRGC), wrote on X on Saturday.

Amid the Houthis’ recent battlefield wins against the fragmented Saudi-backed forces, senior Iranian officials have cheered their Yemeni allies on.

The Houthis’ capture of the port city of Mocha on Friday delivered a huge blow for the Yemeni government, which now has no direct access to the Red Sea.

Mohammad Bagher Ghalibaf, Iranian parliament speaker and chief negotiator with Washington, reposted a comment made by slain Supreme Leader Ayatollah Ali Khamenei in 2024, saying the “resistance” of the Houthis will inevitably lead to victory.

“The brave Yemeni people will certainly triumph, by permission of God Almighty,” Ghalibaf added on Thursday, in Arabic.

Iran’s First Vice President Mohammad Reza Aref said the government is happy with the Houthi advances, and urged leaders in the region to pursue “the rationality of liberation from dependency [from the US and the West], and unity under the banner of Islam”.

The “grand victory” of the Houthis once again proved that “security is not a commodity that can be bought,” added Mohammad Mokhber, an adviser to Iran’s Supreme Leader Mojtaba Khamenei.

How could this benefit Iran?

The Houthis began to attack several vessels in the Red Sea they claimed were linked to Israel in 2023, as part of their stated aim to pressure Israel to end the genocidal war on Gaza.

This prompted bombing campaigns by the US, United Kingdom and Israel against Houthi positions in Sanaa, Hodeidah and other areas.

Saudi Arabia, which joined the war against the Houthis in 2015, has largely stayed out of the current eruption in fighting in Yemen.

After their recent victories, the Yemeni group can now exercise more control over the Red Sea and the Bab al-Mandeb strait.

The Houthis’ control of Yemen’s Red Sea coastline and multiple islands – including the island of Mayun, also known as Perim, sitting about 3km (1.9 miles) off Yemen’s mainland – provides the group with close-range access to the Bab al-Mandeb strait.

A video published on Friday showed a Houthi commander telling soldiers they will no longer need missiles and drones to threaten shipping in the crucial waterway. They could simply position artillery along the coast and fire in all directions at ships, he said.

The Houthis have not declared the strait closed, but the group’s military spokesperson, Yahya Saree, said on Friday that “maritime navigation is safe for all companies except for Saudi vessels.”

Likewise, Iran’s partial control of the Strait of Hormuz on the other side of the Arabian Peninsula has been a key tool of leverage for Tehran in the war against the US.

The prospect of closing down the strait could potentially be used by Tehran in future negotiations over ending the war with the US.

Iranian officials are expected to meet regional Arab representatives on Monday for talks over how to facilitate shipping through the Strait of Hormuz, which Tehran maintains remains closed.

They have said they favour a collective regional approach on passage through the strategic waterway.

Iran claims it has reached an understanding with Oman, which also has territorial waters in the strait.

The US, which has continued its naval blockade of Iran’s ports and intensified sanctions on Tehran, reportedly opposes the agreement.

Authorities in Tehran have signalled there will be no talks with Washington under the current circumstances.

“As long as the American side does not accept all of Iran’s conditions, dialogue and negotiation are of no use,” Ebrahim Azizi, head of the hardline Iranian parliament’s national security commission, wrote on X on Saturday.

‘Lord of the straits’

At the start of the working week in Iran on Saturday, hardline and IRGC-linked newspapers and media outlets celebrated the recent Houthi advances.

Keyhan, whose editor-in-chief was appointed by Ali Khamenei, called the advances “the miracle of resistance” and said they had “put the US and Israel in a bind”.

The Quds newspaper, published by the influential Astan-e Quds Razavi in Mashhad, called Iran and the Houthis “the lord of the straits”.

But even though Tehran has repeatedly threatened that Bab al-Mandeb could be further disrupted if the war continues, Iran’s diplomatic apparatus did not immediately link the Houthi advances with the current fight against the US.

As has often been the case, Iran’s Ministry of Foreign Affairs insisted that the Houthis make their decisions independent of Tehran, with their own interests at heart, including ending Saudi Arabia’s blockade on Yemen.

The Iranian Foreign Ministry also called for an end to the Saudi siege on Houthi-controlled areas, an immediate return to negotiations between the group and Riyadh, and respect for Yemen’s sovereignty and territorial integrity.

The ministry also pushed back on the idea that the Houthis act merely as a proxy for Tehran.

“What is happening now in Yemen is the result of the Yemenis losing patience,” Foreign Ministry spokesman Esmaeil Baghaei told state television on Friday night.

“It is not fair to ignore the fact that they were under a cruel blockade for years, and concluded that the United Nations and regional mechanisms could not resolve the issues.”
