Ukrainian forces destroyed a pontoon bridge and parts of a Russian armored column as it tried to cross a river in the Donbas region, video released by Ukraine's military showed on Friday, and a Russian naval ship was set afire in the Black Sea.
Ukraine has driven Russian troops back from the second-largest city of Kharkiv in the fastest advance since Kremlin forces pulled away from Kyiv and the northeast over a month ago.
Journalists have confirmed Ukraine is now in control of territory stretching to the banks of the Siverskyi Donets River, around 40 kilometers (25 miles) east of Kharkiv. The city, which had been under fierce bombardment, has been quiet for at least two weeks but fighting continued to the north.
