Mecca defence alliance members in Tehran to defuse Iran-US, Yemen tensions 

Tehran, Iran – Ministers and senior security officials from Pakistan, Saudi Arabia and Turkiye – the three nations that signed the Mecca Joint Defence Agreement – are in Tehran to discuss regional security issues amid threats of new US strikes on Iran.

Saudi Defence Minister Khalid bin Salman Al Saud, Pakistani military chief Asim Munir and Turkish intelligence chief Ibrahim Kalin met Iran’s President Masoud Pezeshkian and will discuss tensions with security chief Mohsen Rezaei.

The meetings are among the highest-profile dialogues held in Tehran in recent months. While there is still little information on what might be discussed, the meetings come amid a flurry of diplomatic activity to deal with a new escalation between the United States and Iran.

But analysts broadly believe the visit to Tehran by the three signatories of the Mecca Joint Defence Agreement, a regional defence alliance, will be enough to prevent a new outbreak in violence between the US and Iran.

“The Mecca pact’s 11th-hour visit to Tehran is an attempt to tip the balance in favour of those willing to compromise before the guns start blazing again,” said Ali Vaez, deputy director of the Middle East and North Africa Program at the International Crisis Group.

“But unless they arrive with a credible formula to bridge the US-Iran divide, they may find themselves with little more than goodwill in a race against the clock.”

The talks are expected to address the waves of missile and drone attacks carried out by Yemen’s Houthi rebels, who are allied with Tehran, on Saudi Arabia, which supports Yemen’s internationally recognised government.

“I believe that parties to the Mecca agreement lack options of military engagement with the Houthis, but Riyadh is certainly asserting greater pressure for more, and its expectation of its partners has grown in parallel with the offensive from Yemen,” Ayesha Siddiqa, a senior research fellow in the Department of War Studies at King’s College London, told Al Jazeera.

But despite the collective security arrangement in the Mecca defence pact, Saudi Arabia’s allies Turkiye and Pakistan cannot “afford to commit troops on the ground” in Yemen, said Siddiqa.

The latest diplomatic push is likely linked to visits by Pakistani army chief Asim Munir to Saudi Arabia and Iran last week, Siddiqa said, and coincides with Islamabad’s restrictions on overland border trade with Tehran amid the US blockade on Iran.

Iranian authorities have said they favoured “security originating from within the region” as they prepared for the meetings.

Umer Karim, who researches Saudi foreign policy and its implications for regional security, said the Tehran meetings are unlikely to reduce the risk of a renewed war between Iran and the US, which would likely lead to more regional turmoil.

“Therefore, these talks perhaps are more concerned about the security of Saudi Arabia and involve an attempt by Turkiye and Pakistan to compel Iran to reach a compromise,” he told Al Jazeera.

US President Donald Trump is said to be considering new attacks to break the diplomatic deadlock with Iran, which has refused to agree to any peace agreement with Washington unless several of its demands are met.

The US and regional powers want international shipping and transit through the Strait of Hormuz to resume without impediments or attacks. Washington also wants to rein in Tehran’s nuclear programme and bring in international inspectors to assess Iran’s highly enriched uranium. Israel says it wants to overthrow the Islamic Republic.

Tehran wants to lift the US naval blockade of Iran’s southern ports, which has halted crude oil exports and disrupted most trade, and return to a memorandum of understanding agreed between the two countries in June.

The US has refused this, with President Trump saying he is left with a choice to “finish the job” by launching major strikes on Iran’s civilian infrastructure. This could prompt Iran to lash out at its neighbours, as it did earlier in the war with strikes on US bases in Arab states and infrastructure.

Meanwhile, the US Department of State issued an October 21 order for nonemergency US government employees and their family ⁠members to leave Saudi Arabia for their safety’s sake, given the Houthi threat.

As talks involving Saudi Arabia, Pakistan and Turkiye continue in Iran, analysts say these Mecca Joint Defence Agreement signatories will likely try to minimise the impact on Saudi Arabia if war does break out again.

“However, since little has changed from an Iranian strategic calculus and the actors involved don’t have the kind of leverage needed to affect Iran’s strategic thinking, these negotiations are going to yield little,” Karim said.
