“Well, first, we joined with the European Union and many other like-minded democracies around the world to impose sanctions for what the Russian government has done to Navalny, for the use of a chemical weapon against him, which is in contravention of international laws,” Sullivan said. “Second, we have communicated to the Russian government that what happens to Mr. Navalny in their custody is their responsibility and they will be held accountable by the international community.”

“In terms of the specific measures that we would undertake we are looking at a variety of different costs that we would impose. And I'm not going to telegraph that publicly at this point, but we have communicated that there will be consequences if Mr. Navalny dies,” Sullivan added.
