Ukrainian President Volodymyr Zelensky claimed on Tuesday that the missiles that caused explosions in Poland were fired by the Russian side.
"To fire missiles at NATO territory. This is a Russian missile attack on collective security! This is a very significant escalation. We must act," Zelensky underlined in a video posted on his social media account. He further asserted that Ukraine will stand by Poland, adding that "terror will not break free people."
Earlier, the Russian Ministry of Defense denied that Moscow had anything to do with the alleged attack, stressing that such reports are a "deliberate provocation" aimed at escalating the situation.
