Ministers and senior security officials from Pakistan, Saudi Arabia, and Turkiye convened in Tehran on October 26, 2026, to address regional security concerns, particularly amid escalating threats of new U.S. strikes on Iran. The delegation included Saudi Defence Minister Khalid bin Salman Al Saud, Pakistani military chief Asim Munir, and Turkish intelligence chief Ibrahim Kalin. They met with Iranian President Masoud Pezeshkian and were scheduled to discuss regional issues with security chief Mohsen Rezaei.

These meetings represent some of the most significant diplomatic engagements in Tehran in recent months. The discussions occur amidst intense diplomatic efforts aimed at managing a new phase of escalation between the United States and Iran. Analysts suggest that the visit by the three signatories of the Mecca Joint Defence Agreement, a regional defense pact, is intended to influence the situation towards de-escalation.

Ali Vaez, deputy director of the Middle East and North Africa Program at the International Crisis Group, commented that the visit is an "attempt to tip the balance in favour of those willing to compromise before the guns start blazing again." However, he cautioned that without a concrete plan to bridge the U.S.-Iran divide, the impact might be limited.

A central focus of the talks is expected to be the ongoing missile and drone attacks launched by Yemen's Houthi rebels, who are aligned with Tehran, targeting Saudi Arabia. Saudi Arabia backs Yemen's internationally recognized government, which has been contending with the Houthi advances.

Ayesha Siddiqa, a senior research fellow at King's College London's Department of War Studies, noted that the Mecca agreement signatories might have limited military options regarding the Houthis. She added that Riyadh is likely applying increased pressure for action, with parallel expectations from its partners in response to the offensive from Yemen.

The Mecca Joint Defence Agreement, established to foster collective security among member states, is being tested by the complex regional dynamics. The alliance aims to coordinate responses to threats and promote stability within the region, but navigating the intricate relationships between Iran, the U.S., and various regional actors presents a significant challenge.

While specific details of the agenda remain scarce, the presence of high-ranking defense and security officials underscores the gravity of the regional security situation. The participating nations are key players in the Middle East, and their coordinated diplomatic efforts signal a shared concern over potential conflict.

The outcome of these discussions could significantly influence the trajectory of regional stability, particularly concerning the ongoing conflict in Yemen and the broader tensions between Iran and the United States. The effectiveness of this diplomatic intervention will likely depend on the concrete proposals and commitments made during the meetings.
