(Reuters) - Ukrainian President Volodymyr Zelenskiy's chief of staff called on Monday for a new international security system to preclude future instances of armed aggression, as he addressed an online conference on securing peace following Russia's invasion.
Andriy Yermak said 66 countries and international organisations had taken part in the conference, devoted to one point of the president's peace plan on ending the more than 2 1/2-year-old war with Russia. The discussions focused on future instances of escalation and aggression.
