Russia's ministry of defense released videos showing its troops using 130-mm M-46 howitzers from the 1950s in Kursk.
A large-scale Russian missile and drone barrage on Ukraine on Monday that killed at least five people and ravaged the country's energy infrastructure is estimated to have cost Moscow $1.3 billion.
The nationwide assault, which involved more than 100 missiles and 100 drones, was described by Ukrainian officials as one of the largest launched by Russia since its full-scale invasion of Ukraine began in February 2022.
"Like most Russian strikes before, this one was equally insidious, targeting critical civilian infrastructure," Ukrainian PresidentVolodymyr Zelenskysaid of the attack. "The energy sector has sustained significant damage, but in every area affected by power outages, restoration work is already in progress."
