Most of the drones and missiles were intercepted, according to the Ukrainian Air Force, and there were no immediate reports of widespread damage.

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.

Ukraine unleashed more than a hundred drones smuggled deep into Russia in what it called its most damaging attack yet.
