Renewed Clashes in Yemen’s Decade-Long Conflict: An In-Depth Look at the Warring Factions and Regional Stakes

Yemen’s protracted civil war has entered a perilous new phase following a series of coordinated offensives launched by Houthi rebels against government troops backed by Saudi Arabia. The sudden escalation across multiple domestic fronts has shattered an extended period of relative calm, raising fears that one of the Middle East’s most devastating armed conflicts is reigniting in full force.

The impact of the new offensive quickly crossed Yemen’s territorial boundaries, as Houthi forces directed cross-border strikes into southern Saudi Arabia. These operations targeted energy infrastructure and civilian areas, leaving dozens of people wounded and underscoring the Houthis’ continued capacity to disrupt regional stability and vital oil facilities.

This wave of violence represents the most critical military escalation since the United Nations brokered a nationwide truce in 2022. That historic diplomatic breakthrough had largely paused eight years of continuous, large-scale hostilities that caused tens of thousands of deaths and pushed one of the world’s most impoverished countries into severe humanitarian distress.

Heavy fighting has flared across contested areas, including western Yemen’s Taiz province. On the al-Kadha front west of Taiz city, Yemeni government forces and allied combat groups have engaged in intense firefights against Houthi fighters, utilizing heavy weaponry and rocket-propelled grenades in an effort to repel rebel advances and regain territory.

At the heart of the resurgence is the Houthi movement, officially designated as Ansar Allah, meaning "supporters of God." The group first formed in the 1990s as a Shia Zaidi revivalist movement before gaining widespread prominence a decade ago. In 2014, the rebels launched an armed uprising against the central administration in Sanaa, ultimately forcing the government from the capital and precipitating a nationwide crisis.

Today, the Houthis maintain administrative and military control over significant swathes of Yemeni territory. Their strongholds encompass the capital city of Sanaa, alongside extensive regions across northern and western Yemen situated adjacent to the Saudi border. While the movement aligns with Iran’s broader regional "axis of resistance," it operates with its own distinct leadership, domestic support base, and strategic ambitions.

Over more than a decade of active warfare, the Houthis have systematically expanded their arsenal, displaying advanced unmanned drone and ballistic missile capabilities. They have repeatedly utilized these systems against energy and transport installations inside Saudi Arabia and the United Arab Emirates. The movement has also demonstrated notable operational resilience, withstanding years of coalition airstrikes as well as recent joint bombing campaigns by the United States and the United Kingdom.

Beyond Yemen's borders, the Houthis have significantly increased their international footprint since late 2023. Following the start of Israel’s assault and genocide in Gaza in October 2023, the rebel group initiated high-profile attacks against maritime commercial shipping vessels in the Red Sea and launched projectile strikes aimed at Israeli targets, framing the moves as a regional pressure campaign.

Standing on the opposing side of the primary conflict divide is Saudi Arabia, which formally entered the war in March 2015. Riyadh established and led a multinational military coalition with the stated objective of reversing Houthi territorial gains and restoring the recognized administration of then-President Abd-Rabbu Mansour Hadi to power.

The Saudi intervention was originally driven by deep regional distrust toward Tehran, as Riyadh viewed the emergence of an Iranian-aligned armed authority on its southern border as a critical security threat. While a Beijing-brokered diplomatic agreement between Saudi Arabia and Iran in 2023 helped reduce bilateral tensions and foster a more pragmatic relationship, direct cross-border friction between the kingdom and the Houthis remains an acute risk.

On the political and military frontlines inside Yemen, the anti-Houthi coalition is organized under the Presidential Leadership Council (PLC). Formed in 2022, the executive body was established when former President Hadi officially transferred his presidential authorities to an eight-member leadership council designed to govern the country's defense, security, and administrative apparatus.

Serving as the internationally recognized governing authority of Yemen, the PLC is tasked with leading state institutions and negotiating toward a permanent ceasefire agreement. The council is chaired by Rashad al-Alimi, a former interior minister under the late President Ali Abdullah Saleh and an adviser to Hadi. Backed by Riyadh, the council was assembled from diverse northern and southern military and political factions to present a cohesive front against Houthi forces.

A key domestic component aligned with the recognized government is the Yemeni Congregation for Reform, commonly known as the Islah party. Operating as a Sunni Islamist political and military force with historic connections to the Muslim Brotherhood, Islah holds significant influence within the anti-Houthi coalition while preserving an independent operational identity.

Islah’s primary power base is situated in the strategic Marib governorate. This eastern region is economically vital to the country, serving as Yemen’s exclusive gas-producing territory and housing some of its most substantial commercial oil reserves, making it a persistent target for Houthi military pressure.

Another prominent military formation opposing the rebels is the National Resistance Forces, commanded by Tareq Saleh, the nephew of former President Ali Abdullah Saleh. This faction operates in close coordination with Saudi Arabia and holds formal representation within the Presidential Leadership Council structure.

The National Resistance Forces maintain active combat units across critical southwestern battlegrounds, actively engaging Houthi forces while simultaneously acting as a counterweight against southern secessionist ambitions. Dedicated to preserving a unified Yemeni state, the group's deployments reflect the complex web of local alliances and competing interests shaping the renewed battlefield dynamics across the country.
