Iran has issued its first major public response to the new Saudi Arabia–Turkey–Pakistan defence agreement, with Iranian parliamentarian Ebrahim Rezaei calling it a “paper agreement” that will not bring Riyadh real security. The warning comes as the Mecca Joint Deterrence Agreement pledges that an attack on Saudi Arabia, Turkey or Pakistan will be treated as an attack on all three.
