The United States pulled off a daring rescue of two aviators whose fighter jet was shot down by Iran, plucking the pilot from behind enemy lines before setting off a complicated extraction of the second service member who hid deep in the mountains as Tehran called for Iranians to help capture him.

An Iranian military spokesman claims that a US F-35 fighter jet was shot down over central Iran a short while ago by the Islamic Revolutionary Guard Corps’ air defenses. The spokesperson says there are low chances of pilot survival. Images posted by Iranian media appear to show debris of a US F-15E fighter jet, and not an F-35.
