The fires that broke out in Bryansk, a base for Russia's military operations less than 100 miles from the Ukrainian border, caused no injuries and no plans to evacuate the 400,000 residents of the city.

Russia's Ministry of Emergency Situations only mentioned the first fire at the Transneft oil line, which was holding 10,000 tons of fuel.

Videos of the explosions were uploaded to social media.

What To Watch For

Will the Ukrainians claim responsibility for the incidents? According to The Guardian, a Telegram news channel with ties to Russian security services claimed that the fires were caused by Ukrainian drones. Some people on social media speculated that the fires were caused by a Ukrainian missile strike.

Key Background

The fires came a week after Moscow claimed that Ukrainian helicopters carried out several airstrikes in the Bryansk region that left several injured. In early April, Russia accused Ukraine of attacking a fuel depot in the Russian city of Belgorod near the Ukrainian border, which the Ukrainians denied. Russia bombed five train stations in central and western Ukraine on Monday morning, causing an unknown number of casualties as the country targets the railway infrastructure used to move troops and weapons across the country. Russia said last week that it wanted to take full control of the eastern and southern regions of Ukraine.

There are large fires at Russian oil depots.

Forbes reported that Russia struck five train stations in western and central Ukraine.

The mayor of Russia says the fire almost out.
