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

U.S. military commentators praised Ukraine's "remarkable" Trojan Horse-like use of wooden sheds as it bombed as deep into Russia as Siberia.

The attack has prompted Russian military experts to demand a strong and swift response, including "tactical nuclear strikers" on Ukraine after "Russia's Pearl Harbor," as military blogger Roman Alekhin described it on Telegram. The attack on Pearl Harbor in December 1941 was a surprise air raid by Japan on the U.S. during World War II.
