According to Middle East Eye, citing Turkish officials, as a part of their commitment to the now activated Turkish-Saudi-Pakistani Mecca Joint Defense Agreement, Turkey will deploy troops, air defense systems, and aircraft to Saudi Arabia to defend against increasing attacks on the Gulf nation from the Houthis.
Per the report, Turkey has forces, including technical teams, EW equipment, and aircraft defense systems, already in place since last year under a prior joint exercise agreement that allowed limited Turkish deployments to Saudi Arabia. The Turkish commitment to the Mecca Agreement expands the scale of Turkish deployments, now that the agreement has been activated.
Turkish officials maintain that the deployments are purely defensive in nature.
