Russian forces have attacked Ukraine. Explosions were heard in several cities, including the capital Kyiv, prompting immediate condemnation from the United States and its allies. Russian president Vladimir Putin cast aside international condemnation and sanctions and warned other countries that any attempt to interfere would lead to “consequences you have never seen.” U.S President Joe Biden condemned the attack. Prime Minister Justin Trudeau condemned “Russia’s egregious attack on Ukraine,” warning Moscow of “severe consequences” and additional action by Canada.
