Ukrainian President Volodymyr Zelenskyy said he was “sincerely thankful” to the US for the new round of $800 million in military assistance .
In his daily late-night address to the nation, Mr Zelenskyy also said he was thankful for Wednesday’s visit by the presidents of Poland, Estonia, Lithuania and Latvia.
He said those leaders “have helped us from the first day, those who did not hesitate to give us weapons , those who did not doubt whether to impose sanctions .”
In a phone conversation with US President Joe Biden , Mr Zelenskyy said they discussed the new weapons shipment, even tougher sanctions against Russia and efforts to bring to justice those Russian soldiers who committed war crimes in Ukraine.
He also commented on Russia's military approach, saying: "All this feverish activity of the occupiers testifies first of all to their insecurity.
"To the fact that even with significant stocks of Soviet military equipment and a significant number of soldiers, whom the commanders do not spare at all, the Russian troops doubt their ability to break us, to break Ukraine.
"Well, we do everything to justify their doubts."
