TOKYO -- Ukrainian President Volodymyr Zelenskyy on Wednesday warned Japanese lawmakers in a virtual speech that Russia was escalating its attacks on Ukraine, including possibly employing chemical or nuclear weapons, as he called for tougher sanctions.
"I have received reports that Russia is preparing chemical attacks by using chemical weapons such as sarin," he said in the speech to Japan's parliament. "How would the world react if nuclear weapons are used is also now discussed around the world."
