Türkiye, Saudi Arabia and Pakistan signed an agreement on Friday to reinforce their collective security amid deepening regional crises.
The signing took place in the holy city of Makkah, between Turkish President Tayyip Erdogan, Saudi Crown Prince Mohammed bin Salman and Pakistani Prime Minister Shehbaz Sharif.
The Mecca Joint Defense Agreement, which was in the works since last year, reflects the commitment of participating countries’ to reinforcing their collective security, building on “Islamic solidarity, common strategic interests and close defense cooperation”.
Therefore, the agreement stipulates that “an armed attack against any one of the three countries” will be considered as “an attack against them all”.
It will also enhance defense cooperation across all areas among the three countries.
The Turkish premier posted on X that the agreement targets no country and is open to the participation of all brotherly countries that aim for the peace, prosperity, and stability of its region.
The latest pact is modelled on the security agreement forged between the kingdom and nuclear-armed Pakistan last September, that was carved as a framework of joint deference against aggression.
Whether Türkiye has entered the existing security cooperation agreement as a participant or the three countries have forged a new alliance remains unclear.

The Turkish military ranks as the 9th most powerful out of 145 countries, ahead of Pakistan (14th) and far ahead of Saudi Arabia (25th), according to the Global Firepower Ranking released this year. Pakistan bumped up its defence spending to $9 billion for the 2025-26 fiscal year, up 20% year-on-year.
The trilateral pact coalesces three major economic and military heavyweights – Türkiye, which straddles Europe and Asia, possesses NATO’s second-largest army; Pakistan is the sole nuclear-armed state in the Muslim World; and Saudi Arabia is the largest Arab economy, a financial and energy colossus and home to Islam's two holiest sites.
The agreement lands at a sensitive time as the Mideast region hangs in the balance amid escalating conflicts.
US President Donald Trump held back from launching strikes on Iran on Monday, after reports that the US and Israel were planning a fresh and intense round of attacks.
Meanwhile, Iran has demonstrated its ability to impose costs on the global economic system via the closure of the Strait of Hormuz, a critical chokepoint through which a sizeable portion of energy transits. Talks between Tehran and Muscat on managing and operating the strait are in its final stages.
