Ukraine urges G7 to condemn nuclear threats.

Ukraine's envoy to Japan has urged the G7 leaders to condemn any threat to use nuclear weapons and take decisive action against such a move at their upcoming summit in Hiroshima. The envoy also called for talks on nuclear security and the global architecture, as both the International Atomic Energy Association (IAEA) and the U.N. Security Council lacked power. The envoy's comments came as Russia launched drone, missile and air strikes on the Ukrainian capital, Kyiv, and other cities in the run-up to its cherished Victory Day holiday on May 9 that celebrates the defeat of Nazi Germany.
