Two weeks ago the Ukrainian forces crossed the Ukraine-Russia border and Russia's

west Ukraine's north and you know what looks like a pretty significant incursion.

Isabel Kursion is the Ukraine Bureau Chief for the post. She is reporting on a big turn in the war between Ukraine and Russia.

Ukraine has advanced its troops into Russia for the first time.

Ukrainian soldiers have moved just north of the border, taking control of Russian villages and what's known as the Kursk region.

It's not a short-term raid, as many thought it might be.

They've really turned the tables of this war

more than two years after Russian forces invaded Ukraine

and occupied some 20% of the country.

And I understand that some of our colleagues at the post were able to go with soldiers

into the Kursk region of Russia.

Can you just describe a little bit your sense of

what they were able to see there and what that tells us?

So one of the soldiers that our colleagues talked to who took them across the border, a drone

commander whose call sign is boxer.

He said that...

He said that that this is a little idea

but what the name

I was me with her story

and so talk

we'll just like you know at the beginning he wasn't sure if it was a good idea this incursion into Russia

But as the days progressed you know he realized it was a good idea and they did have an opportunity to end the war with this, that they were doing something historical.
