Hundreds of Ukrainian kamikaze drones have flown towards Moscow in recent weeks. None appear to have even reached the Russian capital, yet the effect on the city — and the wider country — has been hugely significant.

For at least two days in a row, Ukraine has launched massive waves of drones deep into Russian territory. Between the evening of May 20 and the morning of May 22, Russia claims to have shot down 485 drones on its territory.

Moscow is facing a second day of large-scale drone attacks, causing delays for dozens of flights with airports around the Russian capital forced to temporarily halt operations overnight.
