LONDON (Reuters) - A drone has crashed into a military airfield in Russia's Kaluga region, just over 200 km (130 miles) northeast of Ukraine, the region's governor said on Friday.
"Today there was an explosion at the Shaykovka military airfield in Kaluga region," governor Vladislav Shapsha wrote on Telegram.
"A drone, presumably coming from the direction of the border, crashed," he said.
"The airfield infrastructure and equipment were not damaged. There is no threat to operations."
