Saudi Arabia, Turkey and Pakistan are expected to sign a defense agreement on Friday, deepening cooperation between the three regional powers at a time of growing security concerns. This was reported by Qazaqyia.kz citing Associated Press.

The agreement will be signed during a meeting between Saudi Crown Prince Mohammed bin Salman, Turkish President Recep Tayyip Erdogan and Pakistan's Prime Minister Shehbaz Sharif in Saudi Arabia, according to a Turkish security official.

In Pakistan, two officials familiar with the preparations said diplomats from the three countries were fine-tuning a draft agreement covering defense cooperation and other areas that could be endorsed by the leaders of the three countries.

All the officials spoke on condition of anonymity because they were not authorized to discuss the talks publicly.

There were no immediate details of the agreement, which brings oil-rich Saudi Arabia together with nuclear power Pakistan as well as Turkey, which has NATO's second-largest army and a rapidly growing defense industry.

Turkey's Haberturk television said it is likely to allow joint military exercises and training, technology transfers and the sharing of intelligence. Other unconfirmed reports suggested the agreement would state that any aggression against either of the countries would be considered an aggression against all.

Saudi Arabia, whose critical infrastructure and oil facilities have come under attack as part of the war in Iran, has been looking to diversify its defense partnerships.

In September, Pakistan and Saudi Arabia signed a mutual defense pact that defines any attack on either nation as an attack on both.

The agreement also comes amid rising tensions between Turkey and Israel over Gaza and other regional conflicts, including the war in Iran and Lebanon.

Sharif arrived in Saudi Arabia.
