Who are the Houthis?: The Houthis, formally Ansar Allah, are a Zaydi Shia armed movement from northern Yemen. They seized the capital Sanaa in September 2014 and now control territory home to over 70% of Yemen's population. Iran backs them with weapons and training via the IRGC.Source: Lowdown
Why are the Houthis attacking Red Sea shipping?: The Houthis launched over 100 attacks on commercial vessels in the Red Sea from late 2023 to 2025, citing solidarity with Gaza. The attacks halved traffic through Bab al-Mandeb and triggered a major international naval escort operation.Source: Lowdown
Are the Houthis attacking Israel in 2026?: Yes. In late March 2026 the Houthis fired missiles and drones at Israel on three consecutive days. Their deputy information minister also threatened to close Bab al-Mandeb strait as a further escalation step.Source: Lowdown
Can the Houthis close the Bab al-Mandeb strait?: The Houthis control the Yemeni coastline adjacent to Bab al-Mandeb and threatened closure as a staged escalation option. Israeli strikes in 2025 degraded their command-and-control, but launch platforms remain intact, making partial disruption plausible.Source: Lowdown
What is the difference between the Houthis and Hezbollah?: Both are Iran-backed movements within the Axis of Resistance. Hezbollah operates in Lebanon and holds seats in Parliament; the Houthis govern much of Yemen and control strategic Red Sea coastline. Hezbollah has a more sophisticated command structure; the Houthis have greater territorial depth and maritime access.Source: Lowdown
What did the Houthis seize in the Red Sea and why?: The Houthis seized the Galaxy Leader car carrier in November 2023, establishing the precedent for using commercial vessel seizures as coercive diplomacy in support of Iran's Resistance Axis. Iran replicated the tactic directly with the Hui Chuan seizure in May 2026.Source: Lowdown iran-conflict-2026
Could the Houthis close the Bab al-Mandeb strait?: The Houthis control Yemeni coastline flanking Bab al-Mandeb and have explicitly threatened closure. Deputy minister Mohammed Mansour called it 'among our options' in March 2026. Combined with Iran's Hormuz blockade, dual closure would cut roughly 25% of global seaborne energy supply.Source: Lowdown iran-conflict-2026
Who funds and arms the Houthis?: Iran supplies the Houthis with Ballistic Missiles, anti-ship weapons, and drone systems through the IRGC Quds Force. The weapons programme accelerated substantially after 2020.
Are the Houthis still attacking Israel in 2026?: Yes. In March 2026 the Houthis fired on Israel three consecutive days. Their command-and-control capacity was degraded by Israeli strikes in August-September 2025, but launch platforms remain intact and a sustainable attack tempo was demonstrated.Source: Lowdown iran-conflict-2026
What is the connection between the Houthis and Iran's seizure of the Hui Chuan?: Iran's IRGC seized the Hui Chuan floating armoury vessel in May 2026 using the same commercial-vessel-seizure template the Houthis pioneered with the Galaxy Leader in 2023, showing Iran is now executing directly what it previously conducted through its Yemeni proxy.Source: Lowdown iran-conflict-2026

Background

The Houthis, formally Ansar Allah, are a Zaydi Shia armed movement that seized the Yemeni capital Sanaa in September 2014 and now govern territory covering more than 70% of Yemen's population. They survived a decade of Saudi Arabia-led aerial bombardment and built an arsenal of Ballistic Missiles, anti-ship weapons, and drone systems substantially upgraded with Islamic Revolutionary Guard Corps (IRGC) assistance since 2020.

From late 2023 to 2025 the Houthis launched over 100 attacks on commercial shipping through the Red Sea, halving traffic at Bab al-Mandeb and triggering the largest naval escort operation since the Cold War. Their most symbolic action was the seizure of the Galaxy Leader car carrier in November 2023, establishing the precedent that Iran's Resistance Axis would treat commercial vessels as tools of coercive diplomacy. In March 2026 the Houthis opened a new front, firing missiles and drones at Israel on three consecutive days, with deputy information minister Mohammed Mansour explicitly threatening Bab al-Mandeb closure.

On 14 May 2026, Iran itself executed a direct commercial vessel seizure: IRGC personnel took the Hui Chuan, a floating armoury vessel, at anchor 38 nautical miles north-east of Fujairah. The operation mirrored the Galaxy Leader tactically but replaced the proxy with the principal: where the Houthis had demonstrated state-tolerated commercial seizure, Iran demonstrated state-executed seizure. Saudi Arabia, tracking both dynamics, is pressing Washington to end the Hormuz blockade specifically to reduce the incentive for Houthi Bab al-Mandeb escalation. Were both straits closed simultaneously, roughly 25% of global seaborne energy would face disruption.
