Riyadh/Sanaa/Washington -UNS : The conflict in Yemen has entered a new phase of heightened regional tension, with Houthi missile claims, intensified fighting and expanded Saudi military involvement placing renewed scrutiny on the Kingdom’s defence partnerships with the United States, Türkiye and Pakistan.
The escalation is also testing the limits of external support for Riyadh and raising questions about how Washington and its regional partners would respond if attacks on Saudi territory persist.
Before the latest developments, US officials had been monitoring what they regarded as a growing Houthi threat and had warned Riyadh about the potential consequences of a wider military confrontation. The warnings came amid broader tensions between Washington and Tehran.
Iranian President Masoud Pezeshkian described negotiations with the United States as “futile”, while Mohsen Rezaei, secretary of Iran’s Expediency Discernment Council, warned that what he called “any new miscalculation by the enemy” could lead to the opening of new fronts and “major surprises”.
Houthi claims and Saudi air-defence response
The Houthis have claimed responsibility for missile attacks against Saudi targets, including an alleged strike on King Khalid International Airport in Riyadh and an Aramco facility on the Kingdom’s western Red Sea coast.
Early Thursday, Houthi military spokesman Yahya Saree said the group had launched a ballistic missile towards King Khalid International Airport and claimed it had reached its intended target.
Saudi authorities have not independently confirmed that claim. The Saudi-led coalition, however, said its air-defence systems had intercepted and destroyed two ballistic missiles launched towards Riyadh.
The competing accounts underline the difficulty of independently verifying battlefield developments as fighting intensifies.
The missile activity came as forces aligned with Yemen’s internationally recognised government continued an offensive launched on Sunday, with Saudi Arabia participating in the wider military effort.
Houthi-affiliated Al-Masirah television reported Saudi airstrikes in several Yemeni governorates, including against telecommunications facilities in Sana’a and Hodeidah airport, as well as an airstrike in Saada governorate. The reports have not been independently verified.
Military sources told Al-Araby Al-Jadeed that fighting had intensified in several districts of Taiz governorate. Rashad al-Alimi, chairman of Yemen’s Presidential Leadership Council, said the “Dawn of Yemen” operation was advancing towards its objectives, including the restoration of state institutions and recovery of Yemeni territory, including Sana’a.
Türkiye and Pakistan reinforce Saudi defence ties
The escalation has brought renewed attention to Saudi Arabia’s defence arrangements with Türkiye and Pakistan.
Türkiye and Pakistan announced on Monday plans involving military personnel and defence assets in Saudi Arabia under their respective security arrangements with the Kingdom.
Turkish Foreign Minister Hakan Fidan said Thursday that Ankara was examining ways to assist Saudi Arabia in countering Houthi attacks from Yemen under the Mecca Joint Defence Agreement signed by Türkiye, Saudi Arabia and Pakistan.
Fidan emphasised the agreement’s defensive character, stressing that support would be provided when a member state comes under attack rather than as a basis for offensive operations. According to Anadolu Agency, he also said Türkiye would not deploy troops to another country to launch attacks from its territory.
The distinction is significant as Riyadh seeks to strengthen its territorial defences while limiting the risk of a broader regional confrontation.
Syria denies reports of deployment
Syria has meanwhile denied reports of a military movement towards Yemen.
The denial followed a Reuters report that Damascus was considering providing military assistance to Saudi Arabia amid the confrontation with the Houthis.
A Syrian Defence Ministry source told Al-Araby Al-Jadeed that “there is currently no movement of Syrian forces towards Yemen”, providing a direct denial of reports concerning possible Syrian military involvement.
US support remains consequential
Washington remains central to the evolving security picture.
According to The New York Times, US military and intelligence officials had warned Saudi Arabia for months about the Houthi threat and encouraged Riyadh to consolidate forces aligned with the Yemeni government.
The newspaper reported that Washington offered assistance with military planning and intelligence, including information on Houthi force movements, while making clear that its support would not extend to conducting airstrikes itself.
CNN separately reported that more than 100 US military advisers had arrived in Saudi Arabia to assist Riyadh, while the Pentagon was neither directing Saudi air operations nor providing aerial refuelling.
The reported US posture therefore combines intelligence and planning assistance with operational distance from Saudi military action.
Analysis: limits of the Saudi-US partnership
The central question now is whether Washington’s earlier warnings were intended primarily to restrain Riyadh or formed part of a broader framework for limited security cooperation should the situation deteriorate.
For President Donald Trump’s administration, the challenge is to support a key regional partner while avoiding direct involvement in an expanding conflict.
For Crown Prince Mohammed bin Salman and the Saudi leadership, the priority is to strengthen territorial security and support the Yemeni government without allowing the confrontation to widen beyond manageable limits.
Türkiye and Pakistan’s defensive commitments could reinforce Saudi deterrence while preserving political space to avoid direct offensive operations inside Yemen.
