Ukrainian President Volodymyr Zelensky again demanded a fraction of the military hardware from NATO nations on Saturday. Ukraine needed just 1% of NATO's aircraft and 1% of its tanks and would not ask for more, he said. "That is what our partners have, that is what is just gathering dust there. This is all for not only the freedom of Ukraine, but for the freedom of Europe," he said in a late night video address.

Before that Zelensky and Bulgarian PM Kiril Petkov had an online discussion. “Had a constructive conversation with Bulgarian Prime Minister Kiril Petkov, wrote Ukrainian president on Twitter. - Informed (Petkov - ed.) about the course of counteraction to Russian aggression. The critical humanitarian situation in Ukrainian cities and villages was discussed. We have to stop the humanitarian catastrophe together!”

"I was elected to protect the security of Bulgarians and peace in Bulgaria," President Rumen Radev told journalists when asked why Bulgaria and Hungary are not planning to send arms to Ukraine. Bulgarian head of state said that he would not allow the country to get involved in the war. "The price of war is paid by the citizens, not by TV preachers. My concern is the people," Rumen Radev added.

U.S. President Joe Biden said that Russia's leader Vladimir Putin "cannot remain in power" in Warsaw Saturday. However, a White House official said soon after the speech that Biden was not calling for regime change in Russia. The White House clarified that Biden had meant that Putin could not be allowed to exert power over his neighbors or the region.

Russia had been quick to respond to Biden’s initial comment, with Kremlin spokesman Dmitry Peskov saying that such statements limit the possibilities for dialogue between Russia and the US.
