The Mecca Defence Alliance now has a secretariat. Established in Riyadh and announced by Turkish Foreign Minister Hakan Fidan following talks in Istanbul this week, the structure marks the alliance’s first operational institution. Pakistan will supply the first secretary-general. The declaration came after senior officials from all three founding states gathered to begin converting a political commitment, signed August 7, into working procedures and command arrangements.
The Strategic Political and Defence Committee, created under the joint defence agreement, convened to address those operational foundations. The pact’s core clause is unambiguous: an attack on any one of the three states will be treated as an attack on all three. How that clause functions in practice, and under what circumstances it would be invoked, remains unresolved.

The delegations were substantial. Pakistan sent Deputy Prime Minister Ishaq Dar, Field Marshal Asim Munir and Defence Minister Khawaja Asif. Turkiye was represented by Foreign Minister Fidan, Defence Minister Yasar Guler and Chief of the General Staff Selcuk Bayraktaroglu. Saudi Arabia’s team comprised Foreign Minister Faisal bin Farhan Al Saud, Defence Minister Khalid bin Salman and Chief of the General Staff Fayyad al-Ruwaili. Together they addressed military interoperability, joint exercises, defence industrial cooperation and counterterrorism coordination.
Tughral Yamin, a retired brigadier and senior associate at Islamabad’s Institute of Policy Studies, was direct: “an office or secretariat is a must” for the pact to become operational. He pointed to NATO’s Supreme Headquarters Allied Powers Europe, based in Mons, Belgium, as a model for how such structures function. A headquarters was already established in Saudi Arabia following the formation of a separate Saudi-led maritime coalition earlier this year, giving the Riyadh secretariat some institutional precedent to build on.
Sinem Cengiz, a researcher at Qatar University’s Gulf Studies Center, cautioned that institutional details must be clarified before the agreement reaches the Turkish parliament for ratification. The pact’s full terms are unlikely to be made public until that process concludes.
The timing of the Istanbul meeting reflects the pressures driving the alliance’s development. Hours before talks began, Washington and Tehran traded strikes for the first time in a month, resuming a cycle of escalation now extending beyond six months since the US and Israel launched attacks on Iran on February 28. The meeting followed Field Marshal Munir’s fourth visit to Iran this year, during which he met President Masoud Pezeshkian and other senior officials on August 24 as part of Pakistan’s mediation efforts.
Pakistani officials described that Tehran visit as producing significant progress toward reviving a Pakistan-brokered memorandum of understanding and reopening the Strait of Hormuz. The optimism proved short-lived. President Donald Trump stated two days later that the US was “not in a hurry” over talks with Tehran. On Monday morning, US Central Command struck two Islamic Revolutionary Guard Corps rocket launchers on Larak Island in the Strait of Hormuz, its first acknowledged strike on Iran in a month. Iran’s IRGC retaliated within hours, claiming strikes on the King Hussein and al-Azraq airbases in Jordan and the Al Menhad airbase in the United Arab Emirates, though Jordan and the UAE denied the bases had been hit.
That escalation tests the alliance’s coherence directly. Yamin warned that Pakistan’s credibility as both Saudi Arabia’s security partner and Tehran’s trusted interlocutor would become harder to sustain “if the proposed trilateral pact evolves into an explicitly anti-Iran alliance.” Gokhan Ereli, an international relations expert at Istanbul’s Ibn Haldun University, noted that the trilateral relationship predates the current war, pointing to decades-old Saudi-Pakistan security ties and Turkiye’s pursuit of strategic autonomy. The real test, he said, will come once the fighting stops. “If the joint mechanisms, institutional secretariat and industrial coventures outlast the current cycle of escalation, it will confirm that this pact represents a fundamental restructuring of the regional security architecture,” he told Al Jazeera.
Umer Karim, of the Riyadh-based King Faisal Center for Research and Islamic Studies, argued that the war has exposed regional security vulnerabilities extending beyond Iran. “Israel as a strategic hegemon in the region” carries “implications for all three,” he said, referring to Pakistan, Saudi Arabia and Turkiye. That reality became evident days after the Mecca pact signing when Israel struck the Abu al-Duhur airbase in northern Syria, roughly 70 kilometers from the Turkish border, claiming it was preempting a Turkish military deployment. Ankara condemned the strike as an attempt to undermine the trilateral pact.
Expansion is already under discussion. Pakistan’s Foreign Ministry confirmed the pact is open to other states. Dar stated on August 9 that the agreement is defensive in nature and does not replace existing bilateral or multilateral arrangements. Fidan indicated Ankara wants to eventually broaden the framework beyond the three founding members.
Bangladesh has signaled the strongest public interest. State Minister for Foreign Affairs Humayun Kabir said Dhaka has expressed interest and that it would not be unusual for an Islamic country to join such an arrangement. Egypt participated in earlier four-way security talks with the three signatories but did not attend the August 7 signing. Turkish President Recep Tayyip Erdogan told Al Jazeera on August 15 that Cairo’s accession was “possible.” Egyptian Foreign Minister Badr Abdelatty has since said Cairo is weighing constitutional and legal issues before deciding, a reference widely read as touching on Egypt’s existing treaty commitments elsewhere in the region.
Within the Gulf Cooperation Council, former Qatari Prime Minister Hamad bin Jassim Al Thani has publicly urged all six of its states to join. Analysts diverge on likely next entrants. Ereli named Egypt “the most strategically consequential candidate,” citing Cairo’s role as an anchor of Arab diplomacy and its recent rapprochement with Ankara. Cengiz was more skeptical of Egypt’s near-term timeline, grouping it with Syria as contingent on how the pact develops. She pointed instead to Gulf states as more likely near-term movers, naming Qatar, Kuwait and Bahrain. “They already have close relations with the signatory countries,” she said, adding that they favour diversifying their security partnerships beyond the US.
Karim offered a measured closing assessment. “There can be a possibility of either Egypt, Syria or Bangladesh joining,” he said, “but it will take some time to develop the required understandings amongst all stakeholders.” Whether the secretariat in Riyadh can build those understandings while the region remains at war is the question the alliance’s architects have yet to answer.
