President Donald Trump said Saturday that he doubts Russia’s Vladimir Putin wants to end his war in Ukraine, expressing new skepticism that a peace deal can be reached soon. Only a day earlier, Trump had said Ukraine and Russia were “ very close to a deal,” Associated Press reported.

“There was no reason for Putin to be shooting missiles into civilian areas, cities and towns, over the last few days,” Trump said in a social media post as he flew back to the United States after attending Pope Francis’ funeral at the Vatican, where he met briefly with Ukrainian President Volodymyr Zelenskyy.

Trump also hinted at further sanctions against Russia.

“It makes me think that maybe he doesn’t want to stop the war, he’s just tapping me along, and has to be dealt with differently, through “Banking” or “Secondary Sanctions?” Too many people are dying!!!” Trump wrote, according to Associated Press.
