An arms depot was on fire and two drones were shot down in Russian regions bordering Ukraine, local governors said Wednesday.
“According to preliminary information an ammunition depot is on fire near the village of Staraya Nelidovka” around 20 kilometers (12 miles) from the Ukrainian border, the governor of Russia’s Belgorod region said on Telegram.
Vyacheslav Gladkov said the fire had been put out and there were no injuries among civilians or damage to residential buildings.
The cause of the fire was not immediately clear.
Separately, the governors of the neighboring Kursk and Voronezh regions - also near the border with Ukraine - said air defense systems were triggered during the night and shot down drones.
“A Ukrainian unnamed aerial vehicle was intercepted in the sky over Kursk region,” its governor Roman Starovoyt said on Telegram, adding that there were no casualties or damage.
Voronezh region governor Alexander Gusev said on Telegram their air defense system “successfully destroyed” a small reconnaissance drone, without specifying where it came from.
Also in Belgorod region, Russia’s domestic security agency, the FSB, said it detained two Russian citizens who were “preparing to commit sabotage at one of the transport infrastructure facilities.”
It added that they were “supporters of Ukrainian Nazism.”
In a video released by the FSB, one of the suspects - his face blurred on camera - said they were planning to damage a railway line by “unscrewed bolts and loosened fasteners.”
Russia has repeatedly accused Ukrainian forces of launching strikes on its soil, warning that in response Moscow’s troops will intensify attacks on Ukraine’s capital Kyiv.
Officials on Monday had reported that a fuel depot was on fire in the Bryansk region, also near Ukraine.
