Pakistan, Turkey and Saudi Arabia are set to sign a joint defence pact at a leaders' summit in the Saudi city of Jeddah on Friday, Pakistani security sources have told dpa.

Officials familiar with the matter in Islamabad told dpa that the agreement would be signed at a meeting of the leaders of the three countries.

Pakistani Prime Minister Shehbaz Sharif and the country's powerful army chief Asim Munir are already in Saudi Arabia. Turkish President Recep Tayyip Erdoğan left for the kingdom on Friday morning, the state news agency Anadolu reported.

Pakistan and Saudi Arabia have maintained a joint defence agreement since September 2025.

The new agreement is somewhat different in nature, the Pakistani sources told dpa. While the previous agreement focused on the stationing of Pakistani troops in Saudi Arabia, the new pact is oriented towards weapons production - with Saudi money, Turkish technology and Pakistani combat capability combining.

The signing comes amid further military escalation in the Gulf region.

On Friday morning, Saudi Arabia reported casualties from an overnight attack by Yemen's Houthi militia on the kingdom.

According to media reports, Saudi Arabia is preparing for further coordinated attacks by Iraqi militias and the Houthis. Both groups are considered allies of Iran.
