Bryansk

Russian state-owned news agency RIA cited a statement from the Kremniy plant in Bryansk, which said work had been suspended after an attack involving six drones.

Andriy Kovalenko, head of Ukraine's centre for countering disinformation, said on Telegram that an oil refinery in Ryazan had been hit, as well as the Kremniy plant in Bryansk.

It claimed to have destroyed 121 Ukrainian drones, including six over the Moscow region, 20 in the Ryazan region, and a number over the border region of Bryansk.

Strikes in the border region of Bryansk caused explosions at a refinery, ammunition depots and a chemical plant said to produce gunpowder and explosives, a Ukrainian security source told the BBC.

The first attacks using the long-range missiles occurred the following day, with Russian authorities stating at the time that the Bryansk region, which borders Ukraine, had been hit.
