Iran-Houthi tensions have intensified after G7 foreign ministers called on Tehran to end its alleged arming and support of the Houthi movement in Yemen. The warning follows a sharp escalation along Yemen’s Red Sea coast, raising fresh concerns about civilian safety, international trade and global energy security.
The statement was issued during a meeting held on the sidelines of the United Nations General Assembly in New York. Ministers from the UK, Canada, France, Germany, Italy, Japan and the United States condemned Houthi attacks on Saudi Arabia and urged the group to halt military operations against civilian shipping.
Iran-Houthi tensions put Red Sea shipping under pressure
G7 governments said the recent fighting represented a dangerous escalation. They warned that continued attacks could undermine international trade and contribute to wider economic instability, particularly because the conflict is unfolding near the Bab al-Mandab Strait.
The narrow maritime passage links the southern Red Sea with the Gulf of Aden and the wider Indian Ocean. It is a vital route for commercial vessels travelling between Europe, Asia and the Middle East. Houthi control of territory near the strait has therefore raised concerns about shipping delays, insurance costs and the security of energy supplies.
The ministers called on the Houthis to:
- End attacks and threats against civilian shipping
- Stop military action against Saudi Arabia
- Return to negotiations in good faith
- Respect Yemen’s unity, sovereignty and territorial integrity
Iran denies supplying weapons to the Houthis
Iran has repeatedly denied providing weapons to the Houthis, saying its support is political rather than military. However, Western governments have claimed that naval forces have intercepted Iranian weapons shipments allegedly destined for Yemen.
A United Nations panel of experts reported in 2024 that the Houthis had developed into a powerful military organisation through transfers of equipment, technical assistance and training linked to Iran’s Revolutionary Guards, Hezbollah and Iraqi specialists.
The Houthi movement describes itself as part of an Iranian-aligned “axis of resistance” that includes Hamas and Hezbollah. The group has previously framed its military activity as opposition to Israel, the United States and their regional allies.
Conflict brings new displacement
The latest offensive has forced more than 120,000 people from their homes, according to the United Nations. Thousands of Yemenis have reportedly fled towards the Red Sea and neighbouring countries as fighting spread along the coastline.
At least six people, including two children and a woman, were reported killed in Saudi strikes on the port city of Mokha. Eight others were said to have been injured. The city was captured by Houthi forces earlier in the month, while Saudi Arabia has not publicly commented on the reported casualties.
Saudi Arabia seeks military support
Saudi Arabia has responded to Houthi attacks with hundreds of air strikes. The Houthis have launched drones and missiles towards south-western Saudi Arabia, including Riyadh, as well as airports, oil facilities and tankers in the Red Sea.
The UK has agreed to provide defensive air-to-air refuelling support involving a Voyager aircraft based at RAF Akrotiri in Cyprus. France has also indicated that it is prepared to assist with the protection of Saudi energy infrastructure, while maintaining that any contribution would be strictly defensive.
US officials have been weighing a Saudi request for assistance as Washington assesses how to respond to the worsening conflict. New security alerts were issued by US embassies across the Middle East as attacks increased.
Why Yemen’s conflict matters internationally
Yemen’s civil war began in 2014 when the Houthis seized Sanaa and removed the government from the capital. The conflict expanded in 2015 after a Saudi-led coalition intervened to support the internationally recognised government.
An informal ceasefire lasting around four years began to collapse in July. The Houthis then announced a maritime embargo against Saudi Arabia and resumed attacks on airports, oil infrastructure and shipping. The group says its actions are retaliation for restrictions on ports and airports under its control, as well as an air strike on Sanaa airport that it blamed on Saudi Arabia.
Although the Houthis insist they do not threaten international shipping, they have said Saudi-linked vessels remain targets. That position leaves commercial operators facing continued uncertainty in one of the world’s most important maritime corridors.

What happens next?
The G7 statement increases diplomatic pressure on Iran and the Houthis, but it does not by itself provide a clear route to ending the fighting. The immediate priorities remain protecting civilian shipping, preventing further displacement and restoring negotiations.
With the UN General Assembly bringing key leaders together, diplomatic efforts may intensify. However, continued missile and drone attacks, foreign military support and control of territory near Bab al-Mandab could make a return to a political process difficult.
Conclusion
Iran-Houthi tensions have become a serious international security issue, linking Yemen’s humanitarian crisis to the safety of global shipping and energy markets. The G7’s demand for an end to Iranian support reflects growing concern that the conflict could spread beyond Yemen. The clearest path forward is an immediate halt to attacks on civilians and commercial vessels, followed by credible negotiations focused on Yemen’s long-term political settlement.
