A U.S. Air Force F-15 pilot shot down over Iran last June told investigators clearly he saw drones move in strange, bunched patterns.
He described it like sea tentacles flaring then retracting.
Iran has not given a statement on the report.
Stories covered it on The Times of Israel, WION, MSN and Anadolu Ajansı.
The sighting fits into escalating fights between the U.S. and Iran in the skies.
