A drone has exploded outside the Russian city of Kaluga, regional Governor Vladislav Shapsha said on February 6, adding that no one was injured in the blast. "The drone exploded in the air at an altitude of 50 meters in the forest near the city at 5 o'clock in the morning," he wrote on Telegram. Kaluga is about 150 kilometers southwest of Moscow and 260 kilometers from the Ukrainian border. The governor did not make it clear what the source of the drone was. Russia has said in the past that Ukrainian drones have flown into its territory, an assertion that Kyiv denies.
