The Russian Defence Ministry claims to have surrounded Ukrainian troops in Pokrovsk and Kupiansk and says they should surrender to save themselves.
In a statement, it claims:
"Today, the situation of the Ukrainian Armed Forces groups, trapped in the "cauldrons" of Kupiansk and Krasnoarmeysk [Pokrovsk] and continuously suffering significant losses from attacks and the advance of Russian troops, is rapidly deteriorating, leaving no chance for Ukrainian servicemen to save themselves other than voluntary surrender."
These claims have not been independently verified.
Moscow often makes claims about frontline gains that Kyiv disputes.
Russia has been using a pincer movement against forces in both Pokrovsk and Kupiansk, while smaller units and drones attack and disrupt logistics and supply lines.
These tactics created what Russian military bloggers call a grey zone where neither side has full control, but Ukraine struggles to properly defend.
Battlefield maps show Russian forces a few kilometres away from encircling Pokrovsk and in control of a large part of Kupiansk.
Russia's defence ministry has directly contradicted statements from Volodymyr Zelenskyy, instead claiming Ukrainian units were trapped in "cauldrons" and that their position was rapidly deteriorating.
