Joe Biden: 'Very high' risk of Russian invasion in days

President Joe Biden has said there is a "very high" risk of a Russian invasion of Ukraine, which could happen within "several days". Speaking at the White House as he departed for a speech in Ohio, Mr Biden said the United States saw no signs of a claimed Russian withdrawal of forces along its border with Ukraine. He said the US has "reason to believe" that Russia is "engaged in a false flag operation to have an excuse to go in".
