Videos emerging online appear to show a rare, perhaps prototype, Russian Sukhoi S-70 Okhotnik-B (Hunter-B) drone being shot down over Ukraine. Early reporting suggests it may have been a Russian-friendly fire incident after being engaged by other Russian aircraft. That said, as of the time of writing, it is difficult to rule out Ukraine shooting it down. Earlier this year, Ukraine damaged or destroyed a fifth-generation Su-57 Felon fighter jet on the ground.
