The official stated on his Telegram channel that no casualties were reported in the attack and that emergency services are working at the scene.
Once safe access to power facilities is assured, repair and maintenance teams will proceed with recovery, he added.
Bogomaz specified that there will be a bus service for residents of the Suzemka district, which will replace the rail network affected by the bombing until it is restored.
Since Russia launched its special military operation in Ukraine, several border regions, including Briansk, have reported property damage and civilian casualties from shells fired from Ukrainian territory.
Airports in this city and ten others in central and southern European Russia have been closed since February 24.
On October 19, President Vladimir Putin imposed martial law in four newly annexed regions (Donetsk, Lugansk, Kherson and Zaporozhye) and imposed a medium-alert in regions bordering Ukraine.
Likewise, this last measure was applied in the entities sharing a border with the new oblasts: Crimea and Sebastopol, Krasnodar, Belgorod, Briansk, Voronezh, Kursk and Rostov.
The medium alert level provides for certain movement restrictions, vehicle inspections and possible evacuation orders to safe areas.
A high availability regime has been introduced in Moscow and other territorial units in central and southern Russia, and basic availability in the rest of the country.
