Some Russian residents in a town 25 miles from Ukraine are worried about how far Ukrainian troops will advance after pushing Russian invaders back into their own territory.

The residents of Belgorod, a town on the Russian side of the border, told The New York Times that their lives have changed since the war began and that they fear a Ukrainian invasion.

One woman in the town's central market told The Times that it sounded like they were already here. There are rumors that Ukrainian troops are crossing the border for the first time.

Maksim, who sells military and outdoor gear at the market, said people are afraid of rumors. He said his clientele used to be fishermen and hunters.

Bomb shelters are being dug and others are adapting to the reality of missile defense.

The teacher told the Times that working with children makes them feel scared. The children run around screaming'missiles', but we tell them it's just thunder.

After a Ukrainian counteroffensive in the northeast, Russia lost thousands of square miles of territory to the Ukrainians.
