Pompeo: 'substantial chance' senior Russian officials behind Alexei Navalny poisoning

US secretary of state strikes more strident tone after Donald Trump said at the weekend he had not seen any proof of poisoning

The US secretary of state Mike Pompeo has said there was a substantial chance" the poisoning of Kremlin critic Alexei Navalny was ordered by senior Russian officials.

I think people all around the world see this kind of activity for what it is," Pompeo said in a radio interview with conservative host Ben Shapiro. And when they see the effort to poison a dissident, and they recognise that there is a substantial chance that this actually came from senior Russian officials, I think this is not good for the Russian people."
