U.S. intelligence says the drone attack on the Kremlin was part of a covert Ukrainian military or intelligence operation

Video footage showed two drones crashing near the Kremlin earlier this month.

The attack caused little to no damage, and Putin was not at the Kremlin at the time of the strike.

Russia initially blamed Ukraine for the drone attack and then singled out the U.S., accusing the country of giving Kyiv the go-ahead to conduct the operation.
