Ukraine shelling: Biden says 'reason to believe' Russia conducting false flag operation before invasion

President Biden on Thursday said the U.S. has reason to believe that Russia is "engaged in a false flag operation," and said he believes that an invasion into Ukraine "will happen in the next several days."

Tensions have spiked along the line that separates Ukrainian forces from Russia-backed separatists in the country’s east, with the parties accusing each other of intensive shelling.

As he departed the White House, Biden said the threat of a Russian invasion into Ukraine is "very high," and that he believes it could happen "in the next several days."
