Two drones fell on a highway in Russia's Kaluga region that borders with the Moscow region to its north, with the local governor saying on Monday there was no detonation of explosives.
"The area has been cordoned off," the governor of the region, Vladislav Shapsha, said on the Telegram messaging app.
Based on the information provided by Shapsha, the drones fell some 280km-300km (174 miles-186 miles) from Moscow.
Last week, Russia said Ukrainian drones struck wealthy districts of Moscow, which Kyiv denied.
