Russia has declared a state of emergency in part of the Voronezh region bordering Ukraine after an overnight drone attack, local governor Alexander Gusev said in his Telegram channel.
According to Gusev, Russian forces intercepted five drones. Falling debris ignited a fire, leading to the detonation of explosive materials.
The incident damaged no civilian buildings, but prompted authorities to impose emergency measures in three settlements in the Ostrogozhsky district and evacuate 200 people, he said.
