Ukrainian Foreign Minister Dmytro Kuleba said that Tuesday's Russian attacks across shows what Russia thinks about any possible peace negotiations.
"Russian missiles are killing people and ruining infrastructure across Ukraine right now," Kuleba said on Twitter.
Amid reports of Russian missile strikes in multiple locations across Ukraine, Kuleba added: "This is what Russia has to say on the issue of peace talks. Stop proposing Ukraine to accept Russian ultimatums! This terror can only be stopped with the strength of our weapons & principles."
Ukrainian President Volodymyr Zelesnky earlier Tuesday outlined a 10-point peace plan to end Russia's invasion of Ukraine in a video speech to G20 leaders in Bali, Indonesia.
