Social media footage appeared to show rising clouds of black smoke in the Voronezh region while loud explosions could be heard in succession.
Gov. Aleksandr Gusev said that falling wreckage triggered the “detonation of explosive objects.” No casualties were reported, but residents of a nearby village in the Podgorensky district were evacuated, he said. Roads were also closed with emergency services, military and government officials working at the scene.
A Ukrainian security official told The Associated Press that a strike had been carried out on a warehouse storing ammunition in the village of Serhiivka in the Voronezh region.
