Kyiv accused Moscow of breaching its own ceasefire on Thursday, saying Russian forces struck hundreds of times along the front lines and launched guided bombs that killed and wounded civilians in several Ukrainian cities.

U.S. President Donald Trump called on Thursday for a 30-day unconditional ceasefire between Russia and Ukraine and said that both countries will be held accountable for the "sanctity of these direct negotiations.

"Along the way, they’ll once again distort history, claiming that Russia won the Second World War single-handedly. Then, as usual, they will violate their own ceasefire," she says, before adding: "Clearly, it’s a questionable proposal."
