Ukraine has launched a new assault in Russia's Kursk region, six months since Kyiv's surprise incursion into the border area last August.
According to the Institute for the Study of War, a US-based think tank, Kyiv forces have advanced up to 5 kilometres behind Russian lines southeast of Sudzha in Kursk.
The geolocated footage has shown Ukrainian forces moving along the Sudzha-Oboyan highway and already capturing several villages along the way in the direction of Cherkasskaya Konopelka and Ulanok.
Ukrainian authorities are not commenting on the latest developments, while Moscow says the attacks with up to two mechanised battalions' worth of armoured vehicles have been repelled.
