U.S. President Joe Biden announced he would impose "further consequences” on Russia after Vladimir Putin ordered troops into eastern Ukraine, which Biden condemned as an "unprovoked and unjustified attack.”

"President Putin has chosen a premeditated war that will bring a catastrophic loss of life and human suffering,” Biden said in a statement late Wednesday. "The United States and its allies and partners will respond in a united and decisive way.”

Biden said he would outline the punishments in an address to the American people on Thursday, after discussing the unfolding crisis with other Group of Seven leaders in the morning. Administration officials on Wednesday night were still deciding what the next round of penalties would look like, according to a White House official.
