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

Spiegel titled its coverage “Putin’s Pearl Harbor?”and noted that “Ukraine destroyed dozens of Russian strategic bombers in a spectacular drone attack,” asking whether the covert strike might shift the course of the war.

With 41 military aircraft impacted, the Ukrainian drone attack was described by some commentators as Russia's "Pearl Harbor." The attack on Pearl Harbor in December 1941 was a surprise air raid by Japan on the U.S. during World War II. Kyiv's assault follows ground advances by Moscow troops in recent days in Ukraine's Sumy border region.
