(Reuters) -Russian air defence units destroyed 51 Ukrainian drones over the border Belgorod region over a 3-1/2 hour period late on Monday, the Defence Ministry said.
A ministry statement on the Telegram messaging app said the drones were destroyed between 8 p.m. and 11.30 p.m. in the region.
Both Russia and Ukraine have been deploying waves of drones in cross-border attacks against a range of targets in recent weeks.
