Russia says Ukraine has attacked a third bridge in the Kursk region invaded by Ukraine two weeks ago.
It says Kyiv's forces struck and damaged a bridge over the Seym river yesterday.
Details of the latest bridge attack were revealed in a video statement from a representative of Russia's investigative committee, which was posted on the Telegram channel of Russian state TV anchor Vladimir Solovyov.
A Ukrainian commander said yesterday that its air force had destroyed a strategic bridge over the Seym river in Kursk - the second attacked by Ukraine since Friday - limiting the supply capacity of a Russian group opposing the Ukrainian advance.
