All schools and colleges in parts of the Russian region of Belgorod will be closed on Monday and Tuesday following an increase in Ukrainian attacks on the territory, the region’s governor has announced.

Shopping malls will also be closed Sunday and Monday, Vyacheslav Gladkov added in a statement on Telegram. The affected districts lie alongside the border with Ukraine. The city of Belgorod itself is also subject to the closures.

The frequent attacks have brought the war in Ukraine to Russians largely isolated from the conflict.

“The situation is quite difficult both in the city and in Belgorod district. Naturally, the issue of safety is the most important for all of us,” Gladkov wrote.

“It is clear that teachers, nannies and technical staff are all worried,” he said.

Schools and colleges in the affected districts have effectively been closed from Tuesday evening last week, when Gladkov announced students would undertake what he called “days of self-learning” through Friday. At the time of the announcement he said he hoped schools would be able to resume normal activities on Monday.

Ukraine has been attacking the Belgorod region off and on since the first half of 2023 but scaled up shelling and strikes most about a week ago.

As in other parts of Russia, people in Belgorod are voting in a poll widely expected to see Vladimir Putin returned to power as president.

Voting continued for a second day on Saturday, with authorities having arrested several Russians for carrying out acts of civil disobedience.

On Saturday, Gladkov also said two people were killed in early morning attacks, including a truck driver whose vehicle was hit by a shell.

Russia’s Defense Ministry said in a post on its own Telegram channel Saturday that Russian forces had repelled attempts by Ukraine fighters to infiltrate Russia in several locations, saying it had carried out “a complex fire attack on concentrations of enemy manpower and equipment.”

Local residents in Belgorod have been posting videos to regional social media platforms showing explosions in the city and fires burning outside residential buildings where Ukrainian strikes have taken place.

In one video a woman is heard telling her mother she is scared to leave her apartment.

Earlier in the week Ukrainian groups of Russian fighters on Tuesday mounted a cross-border attack in Belgorod while Belgorod city suffered heavy drone strikes and shelling.

At least five people have been reported killed in the last week, according to a CNN count, and several dozen wounded.
