On the night of May 15, Ukrainian drones carried out an attack in the Russian city of Ryazan. According to the statement by regional governor Pavel Malkov, two multi-story residential buildings were damaged and drone parts fell into the area of an industrial facility. Four people, including a child, lost their lives in the attack, and 12 were injured. The drone attack caused a fire at the Ryazan oil refinery, and some locals described the sticky black oil residues covering vehicles, windows, and building facades as 'rain-like falling oil.'
The Ryazan refinery had been targeted by Ukrainian drones before, but this was the first attack resulting in death. The details and effects of the incident may increase tensions in the region.
