Litvinenko suspects

US sanctions five prominent Russians including Litvinenko suspects

Chief federal investigator Alexander Bastrykin and two men wanted in the UK for the murder of Russian dissident Alexander Litvinenko are among them.

The sanctions come amid worsening ties, including claims Russia ran a cyber campaign to influence the US election.

President-elect Donald Trump is seeking to restore closer relations with Russia.

US officials say the sanctions are not related to the hacking but come under a 2012 law designed to punish human rights violators.
