Canadian Prime Minister Mark Carney has urged an immediate ceasefire in Ukraine during a visit to Kyiv for Independence Day celebrations.“We need a cessation of hostilities. We need a ceasefire. We can call it a ceasefire, a truce, an armistice. That’s necessary to stop the killing,” Carney told reporters Sunday, speaking alongside President Volodymyr Zelenskyy.Carney said it was not for Russia to decide the security guarantees Ukraine seeks from Western allies. “It’s not the choice of Russia how the future sovereignty, independence, liberty of Ukraine is guaranteed. It’s the choice of Ukraine and the decisions of the partners,” he said.He condemned Moscow’s invasion and warned that unchecked aggression could spread. “If Russia’s aggression goes unchallenged, it will not stop here,” Carney said, adding that Nato views support for Ukraine as part of collective defense.During his visit, Carney joined Zelenskyy and First Lady Olena Zelenska in laying a wreath at the memorial wall in Kyiv.
