The United States and the European Union have simultaneously imposed punitive measures on Russia.

Washington sanctioned seven senior Russians for poisoning opposition leader Alexei Navalny;

a US intelligence report states that the Russian government is responsible for the poisoning.

"The intelligence agency has confirmed with great confidence that officers of the Russian security agency FSB used the nerve poison novichok to poison Navalny on August 20, 2020," said a US government official.

The sanctions have been imposed in consultation with the European Union.

The EU announced similar measures against the Russian Prosecutor General, the head of the so-called investigative committee under the president's direct responsibility and investigating major criminal cases, the head of the prison system and the head of the national guard, for prosecuting opposition leader Navalny and the crackdown on protests.

The Americans say they do not yet disclose who will receive the sanctions.

Some of the Russians are said to have been designated by Navalny supporters.

The Kremlin critic has been transferred to the Vladimir region, where he is serving a 2.5-year sentence in a penal colony.

Navalny was arrested in Russia after recovering from his poisoning in Germany.

As a result, he could not comply with the notification requirement of a previous lawsuit.

As a result, he still has to serve his suspended prison sentence.
