Saudi Arabia, Turkey and Pakistan formally signed a trilateral defence agreement on Friday, 7 August 2026, declaring that an armed attack on any one of the three nations would be treated as an assault on all three. The deal was unveiled during a meeting in Mecca between Saudi Crown Prince Mohammed bin Salman, Turkish President Recep Tayyip Erdogan and Pakistani Prime Minister Shehbaz Sharif.
According to , regional sources with direct knowledge of the matter confirmed the agreement was finalised on 7 August, describing it as arriving amid what the outlet called "regional turmoil" following Iranian strikes on Gulf states in retaliation for American and Israeli attacks on Iran.
The three governments framed the pact as a defensive measure rather than an aggressive posture. A Turkish official told the Economic Times that the agreement was not aimed at any particular country and remained open to other nations in the region wishing to join. The joint statement reportedly emphasised building "collective deterrence" among the signatories, reaffirming that an armed attack against one member would be considered an attack on all.
Pakistan's foreign ministry echoed this language in its own announcement of the pact, stating:
an attack on any of the three states "shall be regarded as an attack against them all"
Why are these three countries strengthening security ties now?
The push for closer military cooperation comes as fighting between the United States and Iran has spilled into the wider Gulf region, disrupting maritime traffic through the Strait of Hormuz and the Red Sea. Saudi Arabia has found itself increasingly exposed to attacks from Iran-aligned groups since Washington and Israel struck Iranian targets on 28 February.
Our earlier reporting detailed how Saudi Arabia has been weighing whether to escalate or de-escalate as attacks from Iran-backed factions in Iraq and Yemen widened alongside the broader US-Iran confrontation. Separately, we reported that Iran struck a tanker in the Strait of Hormuz as US airstrikes continued into a tenth consecutive night, with Tehran also claiming strikes on American positions in Bahrain, Kuwait and Jordan.
In Yemen, Iran-backed Houthi rebels, who control the northern part of the country, remain locked in conflict with government forces backed by a Saudi-led coalition. Last month the Houthis declared what they called a "maritime embargo" against Saudi Arabia, striking Saudi airports, oil infrastructure and tankers moving through the Red Sea. Our previous coverage noted that the Houthis announced this embargo citing a Saudi blockade, a move that heightened worries over Red Sea shipping safety and the risk of wider escalation. We also reported that these attacks on shipping have fuelled fears of a broader Middle East conflict and added strain to global trade routes.
Riyadh has answered with airstrikes on Houthi positions and by assembling a new naval coalition tasked with safeguarding shipping lanes in the Red Sea and the Gulf of Aden.
How does this pact build on earlier agreements?
This is not the first defence arrangement between the signatories. Saudi Arabia and Pakistan had already struck their own bilateral defence pact in the previous year. noted that this earlier Saudi-Pakistani agreement already stipulated that an attack on either country would be treated as an attack on both, and that it covered "all military means."
The research institute Chatham House has traced the origins of that Saudi-Pakistani pact to September 2025, linking it to what it described as a lack of American response following Iranian drone strikes on Saudi Arabia in 2019 and Israeli attacks on Qatar in 2025, according to a Chatham House analysis. Turkey's interest in joining that alliance was reported as early as January, when Bloomberg described talks on Ankara's membership as advanced, according to a Bloomberg report. Around the same time, Pakistan's minister for defence production said a draft trilateral pact had already been drawn up after nearly a year of negotiations, though Turkey's foreign minister said at that point no formal agreement had yet been signed, according to a separate report from January.
What happens next?
The signing ceremony itself had been anticipated for several days before it took place. had reported that the trilateral agreement was scheduled to be signed in Saudi Arabia on Friday, a timeline later confirmed when the deal was finalised, according to a preview report. NDTV had similarly indicated the signing was expected to take place in Jeddah on Friday, involving Erdogan, Mohammed bin Salman and Sharif, according to an NDTV report.
This report is being updated as further details of the agreement's scope and implementation emerge.
