U.S. actions against Russia include export and visa restrictions, a senior administration official told reporters in a briefing call.

The U.S. intelligence community assessed that officers of Russia's Federal Security Service used a nerve agent known as Novichok to poison Navalny on Aug. 20, 2020, the official said.

Russia has repeatedly denied such accusations,saying the case with Navalny is a purely domestic affair and foreign intervention is not allowed.

"This is an exclusively internal matter. We will not allow anyone to interfere nor intend to listen to such statements," Kremlin spokesman Dmitry Peskov said in January.
