Russian forces shot down “a large number” of drones in Russia’s southern Belgorod region, a local official said on Wednesday, a day after Moscow announced that its forces crushed a cross-border raid in the area from Ukraine.

The drones were intercepted overnight over the province, Belgorod Gov. Vyacheslav Gladkov said in a Telegram post.

He said that no one had been hurt, but unspecified administrative buildings, residential buildings and cars were damaged.

Ukranian officials made no immediate comment.

Russia said the previous day that it beat back one of war’s most serious cross-border attacks, with the Defence Ministry saying that more than 70 attackers were killed in a battle in Belgorod that lasted around 24 hours. It made no mention of any Russian casualties.

Russian Defence Ministry spokesman Igor Konashenkov said that local troops, airstrikes and artillery routed the attackers.

Twelve local civilians were wounded in the attack, officials said, and an older woman died during an evacuation.

Details of the incident in the rural region, lying about 80 kilometres (45 miles) north of the city of Kharkiv in eastern Ukraine and far from the front lines of the almost 15-month war, are unclear.

Moscow blamed the incursion that began Monday on Ukrainian military saboteurs. Kyiv described it as an uprising against the Kremlin by Russian partisans.

It was impossible to reconcile the two versions, to say with certainty who was behind the attack or to ascertain its aims.

The region is a Russian military hub holding fuel and ammunition depots. Moscow officials declined to say how many attackers were involved in the assault or comment on why efforts to put down the attackers took so long.The Belgorod region, like the neighbouring Bryansk region and other border areas, has witnessed sporadic spillover from the war, which Russia started by invading Ukraine in February 2022.

Elsewhere, the Ukrainian General Staff said Wednesday that “heavy fighting” is continuing inside Bakhmut, days after Russia said that it completely captured the devastated city.
