U.S. President Joe Biden must apologize and take back "boorish" allegations that Kremlin leader Vladimir Putin is a killer, a top Russian official said, a day after Moscow recalled its ambassador in protest.

Russian officials on Thursday pointed to the storming of the US Capitol as evidence of America's decline, with one saying it showed US democracy was "limping on both feet".

After the stunning events in Washington, many in Moscow said the United States was no longer in any position to lecture other countries on freedom and democracy.
