Russia-Ukraine crisis updates: U.K. to sanction Russian banks, individuals

Prime Minister Boris Johnson says Britain is slapping sanctions on five Russian banks and three wealthy individuals over Russia's latest military moves on Ukraine.

Johnson told lawmakers that sanctions would hit Rossiya Bank, IS Bank, General Bank, Promsvyazbank and the Black Sea Bank.

He said three Russian oligarchs with interests in energy and infrastructure -- Gennady Timchenko, Boris Rotenberg and Igor Rotenberg -- will have their assets frozen and be banned from travelling to the U.K.

All three have already been sanctioned by the United States.

Johnson accused Russian President Vladimir Putin of "establishing the pretext for a full-scale offensive" against Ukraine and said "further powerful sanctions" would follow if that happened.
