Ukrainian President Petro Poroshenko has called on other nations to help stop Russian aggression in his country, saying that combating such “expansionism” is part of the United Nations’ mission.
Poroshenko used much of his speech before the UN General Assembly on September 26 to lambaste Russia, which annexed Ukraine’s Crimean Peninsula in 2014 and since then has backed a separatist war in eastern Ukraine that has killed more than 10,300 people.
