"We are, in fact, now waiting for a decision from one European capital, which will activate the prepared chains of cooperation regarding tanks," Zelenskiy said in a video address on Thursday night.
German government sources have said Berlin would move on the Leopard tanks issue if Washington agreed to send Abrams tanks to Ukraine.
Ukraine needed the tanks to defend itself, recapture occupied land, and did not plan to attack Russia, Zelenskiy told ARD television on Thursday.
"From Washington to London, from Paris to Warsaw, you hear one thing: Ukraine needs tanks.
Nearby towns also were shelled by Russian forces - including Klishchiivka, just south of Bakhmut, the Ukrainian military said.
