Video posted on social media appears to show Ukrainian troops have retaken territory from Russian forces near the northern city of Chernihiv.
A number of Ukrainian forces are seen in video filmed in the village of Sloboda, about 12 miles (19 kilometers) from Chernihiv.
The village is vital to Ukrainian efforts breaking the Russian encirclement of Chernihiv. It would also be one of the first major victories in breaking the encirclement.
The video has been geolocated and its authenticity verified by CNN.
The footage shows a bombed-out, enflamed Russian tank. Thick white smoke is seen in the streets of the village, in addition to Ukrainian forces.
Some context: Chernihiv, located about 90 miles (145 kilometers) northeast of Kyiv, came under "colossal attack" Wednesday, according to the city's mayor. Strikes also continued in the Kyiv suburbs, just a day after Russia claimed it was scaling back its military campaign near the capital and surrounding area. Russian advances on Kyiv and Chernihiv had already stalled before Moscow's announcement.
