Russian forces prevented a Ukrainian sabotage and reconnaissance team from piercing the border in the western Bryansk region, about 240 km (150 miles) from the site of Ukraine's incursion into the neighbouring Kursk region, a Russian official said, APA reports citing Reuters.
Russia said on Wednesday that its forces had advanced in eastern Ukraine and had begun to push back Ukrainian forces in the Kursk region, though a senior commander cautioned that Ukrainian forces were regrouping for another possible attack.
Bryansk Governor Alexander Bogomaz said that Federal Security Service border guards and Russian military units repelled an attack by a Ukrainian sabotage and reconnaissance team on Wednesday.
He said the attempted incursion took place in the Klimovo district which borders Ukraine's Chernihiv region. The Bryansk region lies northwest of the Kursk region where a Ukrainian incursion has been underway since early August.
Russia's defence ministry said it had shot down 28 drones over Russian territory, including 13 in the Volgograd region, seven in Rostov, four in Belgorod, two in Voronezh and one each in Bryansk and Kursk regions.
