President Volodymyr Zelensky stated this during a briefing on May 19.
"This is my constitutional duty. It is the duty of our military to defend the sovereignty and territorial integrity of Ukraine. Yes, there are currently temporarily occupied territories – due to the aggression of such a large country. That is clear. But there will be no ultimatums, and no one will surrender their land, their territories, their people, their homes", - the president emphasized.
