Russia claims to have thwarted Ukraine’s advance in Kursk

Fighting said to be continuing, with reports of power outages near nuclear power station, despite Moscow's claim

Russia's defence ministry claimed it prevented Ukraine from advancing further on the fifth day of the unprecedented attack into the province of Kursk, though there were reports of regional power outages after an electricity substation was hit.

Fighting was said to be taking place in three villages between seven and 11 miles from the international border - Ivashkovskoye, Malaya Loknya and Olgovka - similar locations to where Ukraine is estimated to have advanced previously.
