An analysis by multiple experts of new video and satellite images suggests that at least 11 Russian bomber aircraft and one large transport plane were badly damaged or destroyed in Ukraine's drone attack on Sunday.

Ukraine said its “Operation Spiderweb” attacked Russian warplanes worth hundreds of millions of dollars, utilizing drones that each cost under $1,000 and were launched from wooden containers carried on trucks.

The images, dated about two weeks apart, show some of the country's prized military assets parked and then destroyed.
