Houthis threaten more Saudi strikes as UN warns of humanitarian crisis in Yemen

Saudi cities faced the threat of a second day of Houthi attacks as fighting across Yemen led the UN to warn of a humanitarian crisis with 100,000 Yemenis already displaced.As oil prices remained well over $100 (£74) a barrel, Qatar warned of a catastrophe if the Iran-backed Houthi militants won full control of the Bab al-Mandab strait, the narrow waterway at the bottom of the Red Sea dominating the key naval route to Asia. The strait has become vital to Saudi crude oil exports as the wider Middle East war chokes the Strait of Hormuz in the Gulf.An emergency meeting of the UN security council in New York heard repeated calls for Houthi forces to show restraint. In a sign that Iran is still seeking a broader solution, its foreign minister, Abbas Araghchi, travelled to Beijing to discuss China’s possible role in solving the related Strait of Hormuz dispute.The future of the Strait of Hormuz – through which a fifth of the world’s traded oil and gas transited in peacetime and which the US and Iran are now mounting blockades of – is the diplomatic key to unlocking the conflict between the US and Iran, and to a lesser extent the related conflict between Saudi Arabia and the Houthis.Oil prices rose sharply after Reuters reported that ⁠loadings at Saudi Arabia’s ⁠Red ⁠Sea port ​of Yanbu had ⁠been suspended, citing shipping industry sources. The price of Brent crude, the international benchmark, rose nearly 3% to $108 a barrel.Prices have risen this week after the ⁠world’s biggest ​crude ‌oil exporter, Saudi Aramco, ‌closed its East-West ‌pipeline due to an attack by Yemen’s Iran-aligned Houthis. Aramco had increased ⁠use of the ​Yanbu terminal since the start of the US-Israel war on Iran in late February.A screen grab from a Houthi video released earlier this week purporting to show militants on an armoured personnel carrier during an offensive near Yemen’s Red Sea city of Mocha.

The planned talks in Oman were delayed at the insistence of Saudi Arabia in protest at what it regarded as Iranian-inspired Houthi attacks on Saudi cities.The Houthis had claimed responsibility for a new “large-scale” attack using “dozens of ballistic missiles and drones” against King Khalid airbase in Khamis Mushait, southern Saudi Arabia, on Monday. Air raid sirens were activated in six governorates including Jeddah on Tuesday. The warnings were lifted relatively quickly, but reflect an unprecedented new state of insecurity across Saudi Arabia.The Oman meeting had been organised with the intention of reaching a regional agreement on an authorised route for commercial shipping through the Strait of Hormuz. The US secretary of state, Marco Rubio, spoke with Oman’s foreign minister, Sayyid Badr Albusaidi, on Tuesday amid US concern that Oman will cede excessive control of the waterway to Iran.A shipping vessel anchored off Yemen’s coast in the Bab al-Mandab strait, pictured earlier this week. Qatar has warned a blockade of the waterway could have a significant impact on world trade.

Houthi leaders have also spoken to the US vice-president, JD Vance, reassuring the White House that their forces are seeking only to hinder Saudi-owned shipping, and that their overall goal is to end what they regard as a Saudi blockade of Houthi-controlled areas. The Houthis have signed a ceasefire agreement with the US, but are still subject to US sanctions.The UK is unlikely to offer direct military, as opposed to political, support to Saudi Arabia unless there is a clear instruction from Washington to do so. Inside Yemen the next military engagement is likely to focus on the city of Marib where Saudi air raids have been trying to weaken Houthi formations.Yemen’s ministry of foreign affairs and expatriates said: “If the world wants stability and calm in the region, it must tell the Saudis: enough interference in the Yemeni affair.”Rather than giving direct military help, western governments are providing intelligence, including targeting advice as well as strategic help in the task of trying to integrate the disparate anti-Houthi forces in Yemen.Houthi forces have been advancing in recent days amid a new offensive.But Maysaa Shuja al-Deen from the Sana’a Centre said: “Any renewed military campaign must be accompanied by a serious reassessment of past mistakes, meaningful reform of the Yemeni government, stronger coordination among anti-Houthi forces, and a more balanced relationship between Yemeni actors and their regional partners.”She added: “In many cases, the Saudis choose Yemeni figures who are weak, easily manipulated, and willing to follow their orders. If they instead chose competent, strong actors who could implement a shared agenda, they would also gain the respect of other competent Yemeni figures.“This approach contrasts with the Iranian and Emirati models, which have generally given their local allies more room to manoeuvre while building relationships around specific objectives and clearer mandates.”Due to the weakness of the UN-recognised government in Yemen, various militias with different ideological or regional loyalties operate alongside the official national army. Together on paper, the number of anti-Houthi forces could reach as many as 500,000 troops but in practice not all these forces cooperate or are willing to fight outside their area.Saudi Arabia gives support to Yemen’s Homeland Shield Forces while the United Arab Emirates had backed both the 80,000-strong Southern Transitional Council’s Giants Brigade and a 20,000-strong force led by Tareq Saleh. But the UAE, after backing separatist forces in the south, has now pulled out of Yemen.
