significant developments this morning in Ukraine's efforts to hit back against Russian aggression.

Ukraine launched a massive drone attack deep inside Russian territory.

The New York Times calls it a coordinated operation that targeted sites from eastern Siberia

to Russia's western border.

A source in Ukraine Security Service tells NBC News that more than 40 Russian bomber planes

were targeted in an operation nearly 3,000 miles away from Ukraine.

The mission, codenamed Spider-Web, is estimated to have cost Russia more than $2 billion worth of damage to its plane.

Two billion.

The attack was planned over the course of the past year and a half and involved a

meticulous method of first smuggling the drones deep into Russia and then disguising them

so they could be activated remotely. Sounds like a movie. NBC News cannot independently verify

the claims made by the Ukrainian source.

However, Russia's defense ministry confirmed the attacks.

Stay away. Stay away. He's right there. He's throwing my outside.

He's right there.

He's both of this. You're on the ground now!

Are you ground?

Where are you?

You don't attack you like that.

You call to shit.

He's not right.
