Senior officials from Pakistan, Saudi Arabia and Türkiye are expected to meet Iranian officials in Tehran on Monday to discuss regional security and coordination, according to Iranian officials and Reuters.

Ali Bagheri Kani, deputy secretary of Iran’s Supreme National Security Council, said Saudi Defence Minister Khalid bin Salman and Türkiye’s intelligence chief Ibrahim Kalin would participate in the meeting with Iran’s security chief, Mohsen Rezaei.

Kani described the four-party meeting as a potential step towards establishing lasting regional security, but did not provide further details.

Pakistan, Saudi Arabia and Türkiye have a trilateral defence agreement known as the Makkah Joint Defence Agreement. The pact states that an armed attack on one member would be considered an attack on all three countries and commits the parties to using necessary means to address threats to their territorial integrity, sovereignty and internationally recognised borders.

The agreement was signed in August amid a regional conflict that began in February, when the United States and Israel launched strikes on Iran during nuclear negotiations between Washington and Tehran.

A ceasefire brokered by Pakistan in April ended the initial phase of intense bombardment, but tensions have continued over control of the Strait of Hormuz, a key route for global oil and liquefied natural gas shipments.

Iran has claimed control over the strait and has targeted vessels attempting to cross without its authorisation, while the United States has imposed a naval counter-blockade on Iranian ports.

Diplomatic efforts between Washington and Tehran remain stalled following the collapse of a June agreement aimed at establishing a permanent settlement. The conflict has also spread across the region, including fighting between Saudi Arabia and the Houthis in Yemen.

The Tehran meeting is expected to focus on regional security and coordination amid continuing tensions.
