On Monday, the governor of the Bryansk region, Alexander Bogomaz, announced on Telegram that the Ukrainian armed forces had carried out a drone attack on a government building in the region of Trubchevsk overnight.
The attack caused damage to the roof and windows of the building, but there were no casualties.
The Bryansk region is in the northern part and slightly to the east of the Ukrainian border.
In the Rostov region, Governor Vasily Golubev also reported destruction in the settlement of Daraganovka after an incident with a drone.
The area is about 105 kilometres east of Mariupol in southern Ukraine.
The Russian Ministry of Defence was in the process of clarifying the drone’s origins.
A house and a car were damaged, Mr Golubev said, but no one was injured.
Videos circulated on social networks of the destroyed building after an explosion, with smoke rising from the rubble.
Residents reported massive damage.
Russia has been waging a full-scale war against Ukraine since February 2022 and has attacked the country with massive missile and drone strikes, among other weapons.
Russia’s border regions had repeatedly complained of attacks from the Ukrainian side, with minimal casualties and damage in these areas compared to the Russian destruction of Ukraine.
Moscow consistently blames Kyiv for the shelling in the border region.
Over the weekend, Moscow was again the target of drone attacks.
Kyiv had not officially admitted any involvement in these attacks.
