From the Mecca defence pact to Tehran talks: Is the Middle East’s security landscape shifting?

Senior officials from Saudi Arabia, Pakistan, and Turkey are meeting with Iranian representatives in Tehran, amid ongoing diplomatic efforts to reduce tensions between Iran and the United States. These three nations are members of the Mecca Defence Alliance, a security pact established amid regional instability and concerns over threats linked to Iran and its allies.

The three nations have now initiated direct talks with Tehran regarding regional security, even as the alliance confronts increasing pressure from Houthi attacks by Yemen's Iran-aligned group on Saudi Arabia. The Saudi Defence Minister, Pakistani Army Chief, and Turkish Intelligence Chief are attending the Tehran talks, scheduled for Monday, according to Saudi and Iranian officials.

Iranian Foreign Ministry spokesman Esmaeil Baghaei described the meeting as a potential step towards establishing cooperative regional security mechanisms, reiterating Iran's call for "endogenous security" - a framework relying primarily on regional countries' capabilities and interests. At a press conference in Tehran, Baghaei reiterated Iran's longstanding plea for this approach.

The Mecca Defence Alliance, signed in August 2026, brought together Saudi Arabia's financial resources and global energy influence, Pakistan's nuclear capabilities, and Turkey's advanced defense industry and NATO membership. While the pact was signed amid concerns over Iran, Turkish officials insist it is not aimed against any specific country, stating that countries are considered targets only if they attack a signatory.

Escalating missile and drone attacks by Yemen's Houthis against Saudi Arabia have tested the Mecca alliance's collective defense measures for the first time. At an emergency Saudi meeting, the three countries agreed to implement their defense commitments, which include rapid deployment of military forces to Saudi Arabia. However, Turkey ruled out sending troops to Yemen to carry out attacks, focusing instead on areas like air defense, electronic warfare, and technical assistance.

The dual approach of pursuing direct dialogue with Iran alongside the alliance's military readiness is noteworthy, but significant differences remain. Saudi Arabia maintains security ties with the United States, Turkey is a NATO member, and Pakistan pursues defense partnerships with several major powers. Despite this, the Tehran meeting signifies a significant development: Three countries establishing a mutual defense alliance are now engaging in direct talks with Iran, raising questions about whether this approach can impact regional tensions in the long run.
