Why Are the Houthis Attacking Saudi Arabia? Yemen Conflict, Iran Links and Red Sea Crisis Explained
The renewed Houthi attacks on Saudi Arabia are rooted in Yemen’s unresolved civil war, the history of Saudi military intervention, the Houthis’ growing regional military power and their relationship with Iran. The latest escalation has added another dimension: control of Yemen’s Red Sea coast and the strategic Bab al-Mandab Strait.
After several years of relative calm between Saudi Arabia and Yemen’s Houthi movement, missiles, drones and air strikes have again brought the two sides into direct confrontation.
The escalation in September 2026 has been particularly significant. Houthi forces have made major territorial gains along Yemen’s Red Sea coast, while Saudi Arabia has carried out air strikes in support of forces aligned with Yemen’s internationally recognised government. The Houthis, meanwhile, have launched missiles and drones towards Saudi territory.
But why are the Houthis attacking Saudi Arabia again?
The answer goes far beyond the latest drone strike. The conflict stretches back more than a decade and involves Yemen’s civil war, Saudi security interests, Iranian support for the Houthis and control over one of the world’s most important maritime corridors.
Why Are the Houthis Attacking Saudi Arabia Now?
The immediate escalation is closely connected to renewed fighting inside Yemen.
The Houthis, formally known as Ansar Allah, have expanded their control along Yemen’s western Red Sea coast. Reuters reported in September 2026 that Houthi forces captured Mocha and subsequently extended their control along the coastline overlooking the Bab al-Mandab Strait.
Saudi Arabia supports forces aligned with Yemen’s internationally recognised government and has responded with air strikes against Houthi positions.
The Houthis, in turn, have resumed attacks against Saudi Arabia.
There is also a wider regional dimension. The Houthis have presented themselves as part of a broader regional front aligned with Iran and opposed to Israel and the United States. During the Gaza war beginning in 2023, they attacked international shipping in the Red Sea and fired missiles and drones towards Israel, saying their operations were in solidarity with Palestinians.
In 2026, regional tensions involving Iran have again become part of the backdrop to Houthi military activity.
However, describing the Houthis simply as an Iranian proxy would obscure an important part of the story: they are also a Yemeni movement with their own political, territorial and military objectives.

Who Are the Houthis?
The Houthis emerged from Yemen’s northern Saada region.
Their roots lie in a Zaydi Shia religious revival movement that developed during the 1990s. The movement was associated with the Houthi family and became increasingly opposed to Yemen’s central government.
Between 2004 and 2010, the Houthis fought a series of wars against the government of then-president Ali Abdullah Saleh.
The political upheaval caused by the Arab Spring transformed the balance of power.
Saleh eventually left office, but Yemen’s political transition remained unstable. The Houthis exploited the weakening of the state and expanded beyond their traditional northern strongholds.
In September 2014, Houthi fighters seized Sana’a, Yemen’s capital.
Their advance fundamentally changed the conflict.
By early 2015, President Abdrabbuh Mansur Hadi had fled Sana’a, and Houthi forces
continued moving south.
Saudi Arabia viewed the development as a major security threat on its southern border.
That brought Riyadh directly into the war.
Why Did Saudi Arabia Enter the Yemen War?
On March 26, 2015, Saudi Arabia launched a military intervention in Yemen at the head of an Arab coalition.
The stated objective was to restore the internationally recognised government and halt the Houthi advance.
Saudi Arabia had several strategic concerns.
First was border security. Yemen shares a long frontier with Saudi Arabia, and Riyadh did not want a hostile armed movement controlling large areas immediately to its south.
Second was the Houthis’ relationship with Iran.
Saudi Arabia and Iran had long competed for regional influence. The emergence of a heavily armed movement with Iranian ties along Saudi Arabia’s border was therefore viewed in Riyadh as a strategic challenge.
Third was Yemen itself.
Instability in Yemen could affect Saudi territory, shipping routes and energy infrastructure.
The intervention was initially expected to be relatively short.
Instead, the war dragged on for years.
UPDATED+ | YEMEN CONFLICT TIMELINE
How Did the Houthis Become Capable of Striking Saudi Arabia?
One of the most important developments during the Yemen war was the transformation of Houthi military capabilities.
The movement began as a relatively local insurgency.
Today, it possesses ballistic missiles, drones and other weapons capable of striking targets hundreds — and in some cases more than 1,000 kilometres, away.
Reuters reported that Houthi ballistic missiles have demonstrated ranges extending beyond 1,000 miles, while drones have repeatedly been used against Saudi targets and increasingly on Yemeni battlefields.
Saudi cities, airports and energy infrastructure have previously been targeted.
The transformation means Saudi Arabia no longer faces only an insurgency across its border.
It faces an armed organisation capable of conducting long-range asymmetric warfare.
What Role Does Iran Play?
Iran is one of the most important external factors in understanding the rise of the Houthis.
Tehran has developed close relations with the movement, while UN investigators and Western governments have documented or alleged transfers of weapons technology, components, training and other forms of assistance.
Reuters reports that UN experts have pointed to training and technical assistance involving Iran and Hezbollah.
Iran has denied violating the UN arms embargo on Yemen.
The relationship nevertheless gives Tehran a strategically significant partner near Saudi Arabia and alongside the Red Sea.
But the relationship requires nuance.
The Houthis are not simply an organisation created by Iran.
Their origins lie inside Yemen, their insurgency predates much of their current relationship with Tehran, and their leadership pursues its own domestic political and territorial objectives.
Iranian assistance has helped strengthen their capabilities, but that does not establish that Tehran directly controls every Houthi military decision.
UPDATED+ | IRAN–HOUTHI CONNECTION
What is established?
The Houthis and Iran have developed increasingly close political and military relations.
What has been reported?
UN investigators and Western governments have reported Iranian-origin weapons, components, technology and training connected to Houthi capabilities.
What does Iran say?
Iran has denied violating the UN arms embargo.
Important distinction
Iranian support does not automatically mean every Houthi operation is ordered directly by Tehran.
Why Is Bab al-Mandab So Important?
Geography is one of the biggest reasons the Yemen conflict matters internationally.
At Yemen’s southwestern edge lies the Bab al-Mandab Strait.
The narrow waterway connects:
Indian Ocean → Gulf of Aden → Bab al-Mandab → Red Sea → Suez Canal → Mediterranean
It is therefore part of one of the principal maritime routes linking Asia with Europe.
At its narrowest point, the strait is roughly 19 miles, around 30 kilometres wide.
Houthi advances along Yemen’s Red Sea coastline in September 2026 have increased their ability to threaten shipping passing through the area. Reuters reported that their territorial gains put forces along the coastline overlooking the strait.
That changes the strategic significance of the Yemen war.
What began as a domestic conflict can directly affect international shipping.
Why Bab al-Mandab Matters in the Saudi - Houthi Conflict
Why Do the Houthis Target Saudi Oil and Energy Infrastructure?
Energy infrastructure provides Saudi Arabia with enormous economic and strategic importance.
That also makes such infrastructure a high-impact target.
During previous phases of the Yemen conflict, Houthi missiles and drones targeted Saudi airports, oil installations and other infrastructure.
Attacking energy facilities can create effects far beyond the physical damage itself.
Even limited disruptions can raise concerns about:
Saudi production and export capacity
regional energy security
tanker routes
shipping insurance
global crude prices.
Saudi Arabia is also one of the world’s major oil exporters.
Consequently, attacks on Saudi energy infrastructure can rapidly become an international economic issue.
Did the Houthis Try to Attack Mecca?
This is one of the most sensitive questions arising from the latest escalation, and the available claims must be distinguished carefully.
Saudi Arabia said its forces intercepted a Houthi drone south of Mecca on September 15, 2026, before it entered the city’s prohibited airspace.
Saudi authorities described the incident as an attempted attack on the holy city.
The Houthis deny that account.
Houthi leader Abdel-Malik al-Houthi has rejected the Saudi allegation that his movement targeted Mecca.
Therefore, it would be inaccurate to state as an independently established fact that the Houthis deliberately attempted to strike Mecca.
The accurate formulation is:
Saudi Arabia says the drone was headed towards Mecca; the Houthis deny targeting the holy city.
The incident is particularly sensitive because Mecca is Islam’s holiest city and receives millions of Muslim pilgrims.
India also expressed concern about the incident, noting Mecca’s significance to Muslims worldwide.
UPDATED+ | CLAIM vs CONFIRMED
SAUDI CLAIM
A Houthi drone was heading towards Mecca.
CONFIRMED
Saudi forces reported intercepting a drone south of the city.
HOUTHI POSITION
The Houthis deny targeting Mecca.
WHAT REMAINS DISPUTED
The intended target of the drone has not been independently established.
What Happened in Taif?
The escalation has also produced civilian casualties inside Saudi Arabia.
On September 17, Saudi authorities said debris from an intercepted Houthi drone fell in Taif, killing a Yemeni resident and injuring two other people.
Reuters described it as the first death announced by Saudi authorities during the latest wave of Houthi attacks.
The incident demonstrates another risk associated with missile and drone warfare.
Even when an incoming weapon is intercepted, falling debris can cause casualties and property damage on the ground.
Why Did the 2022 Truce Matter?
The current escalation is significant partly because Saudi Arabia and the Houthis had moved away from direct large-scale confrontation.
A UN-mediated truce began in April 2022.
Although the formal truce expired later that year, many of its key effects survived.
Cross-border attacks fell dramatically.
Saudi Arabia and the Houthis subsequently held negotiations aimed at creating a more durable settlement.
For several years, Riyadh appeared increasingly focused on finding a political exit from the Yemen conflict rather than returning to large-scale warfare.
The renewed fighting in 2026 has disrupted that trajectory.
Reuters reported that fighting has again emerged along several established Yemeni fronts, including Marib, Jawf, Taiz, Dhale and the Red Sea coastal region.
Is This Still Just a Yemen Civil War?
Increasingly, no.
The conflict began primarily as a struggle over political power inside Yemen.
But several layers now overlap.
There is still a Yemeni civil war between rival political and military forces.
There is also a Saudi–Houthi security conflict.
There is an Iran–Saudi regional dimension.
The Houthis' attacks on Israel and Red Sea shipping introduced an Israel–Gaza dimension.
And control over Bab al-Mandab gives the conflict a direct connection to global trade and energy security.
That combination explains why developments inside one of the Arab world's poorest countries can affect governments and businesses thousands of kilometres away.
Could the Conflict Disrupt Global Oil Supplies?
It could increase risks to energy markets, although disruption is not automatic.
There are two separate vulnerabilities.
The first is Saudi energy infrastructure.
Missile or drone attacks against oil facilities can temporarily affect operations or create concerns about future supply.
The second is shipping.
Saudi oil exports can move through maritime routes connected to both the Persian Gulf and Red Sea.
If insecurity increases around Bab al-Mandab, tankers and commercial vessels may face higher insurance costs, delays or rerouting.
Markets therefore watch Saudi–Houthi escalation closely even when actual oil production remains largely unaffected.
Why Does the Saudi–Houthi Conflict Matter to India?
For India, the conflict is geographically distant but economically important.
India depends heavily on imported crude oil and maintains extensive trade and economic relations with Gulf countries, including Saudi Arabia.
Three areas matter particularly.
1. Oil prices
A sustained regional conflict that disrupts energy infrastructure or shipping could put upward pressure on global crude prices.
For an oil-importing economy such as India, higher crude prices can increase the country's import bill.
2. Shipping
The Red Sea–Suez route is an important connection between India, Europe and the Mediterranean.
Ships avoiding the Red Sea may instead travel around the Cape of Good Hope, adding distance and potentially increasing freight and insurance costs.
3. Indians in the Gulf
Millions of Indians live and work across Gulf countries.
Any broader regional escalation therefore carries a significant consular and human-security dimension for New Delhi.
This helps explain why India closely follows security developments involving Saudi Arabia and the wider Gulf.
What Happens Next?
Several developments will determine whether the confrontation escalates further or returns to diplomacy.
The first is the battlefield inside Yemen.
If Houthi forces consolidate territorial gains along the Red Sea coast, Saudi Arabia and Yemen’s government-aligned forces will face difficult strategic choices.
The second is Bab al-Mandab.
Any sustained disruption of commercial shipping would increase international pressure for a diplomatic or security response.
The third is Iran.
Iran’s relationship with the Houthis means developments involving Tehran and other regional powers can affect the broader security environment, although Houthi decision-making should not automatically be treated as identical to Iranian policy.
Diplomatic channels have also not completely disappeared. Reuters reported on September 16 that US officials had recently met Houthi representatives in Oman, illustrating that negotiations are continuing alongside military escalation.
The situation therefore remains fluid.
The Bigger Picture
The latest Houthi attacks on Saudi Arabia cannot be understood as an isolated series of drone strikes.
They are the latest phase of a conflict that has evolved for more than a decade.
The Houthis have moved from being a northern Yemeni insurgency to controlling large areas of the country and possessing missiles and drones capable of reaching targets far beyond Yemen.
Saudi Arabia entered the war in 2015 primarily to prevent the movement from consolidating power along its southern border and to support Yemen’s internationally recognised government.
Iranian assistance subsequently strengthened the Houthis' military capabilities, while the Red Sea crisis expanded their strategic reach.
Now Bab al-Mandab has become central to the story.
Control of territory overlooking one of the world's major shipping routes means another round of fighting in Yemen could have consequences far beyond the Arabian Peninsula — including for global shipping, energy markets and countries such as India.
For that reason, the renewed Saudi–Houthi confrontation is no longer only about who governs Yemen.
It is increasingly about who can influence one of the world's most strategically important corridors.
