ISLAMABAD, May 18 (Reuters) - Pakistan has deployed 8,000 troops, a squadron of fighter jets and an air defence system to Saudi Arabia under a mutual defence pact, ramping up military cooperation with Riyadh even as Islamabad serves as the main mediator in the Iran war.
The deployment, the full scale of which is reported here for the first time, was confirmed by three security officials and two government sources, all of whom described it as a substantial,
combat-capable force intended to support Saudi Arabia's military if the kingdom comes under further attack.
Pakistan's military and foreign office and Saudi Arabia's government media office did not respond to requests for comment on the deployment.
The full terms of the defence agreement, signed last year, are confidential, but both sides have said it requires Pakistan and Saudi Arabia to come to each other's defence in the event of an attack. Defence Minister Khawaja Asif has previously implied that it places Saudi Arabia under Pakistan's nuclear umbrella.
According to the sources, Pakistan has deployed a full squadron of around 16 aircraft, mostly JF-17 fighters made jointly with China, which were sent to Saudi Arabia in early April. Two of the security officials said Pakistan had also sent two squadrons of drones.
All five sources said the deployment includes around 8,000 troops, with a pledge to send more if needed, as well as a Chinese HQ-9 air defence system.
The equipment is operated by Pakistani personnel and financed by Saudi Arabia, they said.
THOUSANDS OF TROOPS
The military and air force personnel deployed during the Iran conflict will primarily have an advisory and training role, according to two of the security officials, who said they had seen exchanges between the two countries and documents on the military assets' deployment.
The deployment adds to thousands of Pakistani troops with a combat role that were already stationed in the kingdom under previous agreements, all three security officials said.
One of the government sources, who has seen the text of the confidential defence pact, said it provides for the possibility of up to 80,000 Pakistani troops being deployed to Saudi Arabia, to help secure the kingdom's borders alongside Saudi forces.
Two of the security officials said the agreement also involved the deployment of Pakistani warships. Reuters was not able to determine whether any had reached Saudi Arabia.
The scale and composition of the deployment — combat aircraft, air defences and thousands of troops — mean Pakistan has sent far more than a symbolic or advisory mission, the sources said.
Reuters previously reported that Pakistan had sent jets to Saudi Arabia after Iranian strikes hit key energy infrastructure and killed a Saudi national, raising concerns that the Gulf kingdom might retaliate heavily and widen the conflict.
This took place before Islamabad emerged as the war's principal mediator, helping to broker a ceasefire between Washington and Tehran that has held for the past six weeks. Islamabad hosted the only round of U.S.-Iranian peace talks so far, and had planned further rounds which the sides called off.
Reuters has since reported that Saudi Arabia launched numerous unpublicized strikes on Iran in retaliation for attacks carried out inside the kingdom.
Pakistan has long provided military support to Saudi Arabia, including training and advisory deployments, while Riyadh has repeatedly stepped in to support Islamabad financially during periods of economic stress.
