President Vladimir Putin said on Tuesday Russian troops would push further into Ukraine to build on their success on the battlefield after the fall of the town of Avdiivka where he said Ukrainian troops had been forced to flee in chaos.

Gerasimov was shown awarding medals to Russian troops involved in taking Avdiivka and he was given a report by the commander in charge of the Russian assault on Avdiivka, Colonel-General Andrei Mordvichev, state media said.

Ukrainian Foreign Minister Dmytro Kuleba told CNN that Avdiivka would not have fallen had Kyiv received weapons held up by the U.S. Congress' failure to approve a large aid package.

After the failure of Ukraine to pierce Russian front lines in the east and south last year, Moscow has been trying to grind down Ukrainian forces just as Kyiv ponders a major new mobilisation.
