Biden, Putin begin talks, RIA says, after U.S. warning of toughest sanctions yet if Russia invades Ukraine


U.S. President Joe Biden began a video conference with Russian President Vladimir Putin on Tuesday, Russian state television said, after U.S. officials warned Moscow could be hit with the toughest economic sanctions yet if it invades Ukraine.

The officials said the sanctions, which one source said could target Russia’s biggest banks and Moscow’s ability to convert roubles into dollars and other currencies, were designed to dissuade Putin from using tens of thousands of troops massed near the Ukrainian border to attack its southern neighbour.
