Makkah Joint Defence Agreement: MECCA — In a monumental shift for regional security, Saudi Arabia, Turkey, and Pakistan officially signed a sweeping joint defence pact on Friday. Formalised at the Al-Safa Palace during the Makkah Summit on Joint Defence, the historic agreement—known as the Makkah Joint Defence Agreement—commits the three nations to a mutual defense doctrine: an armed attack against any one of the three will be officially treated as an attack against them all.
