The US has responded to President Putin’s order putting Russia’s nuclear forces on a “special” state of alert.
The move makes it easier to launch weapons – but our security correspondent Gordon Corera said it was a way for Russia to send a warning to Nato, rather than signalling an intent to use them.
The US Ambassador to the United Nations, Linda Thomas-Greenfield, called the move “unacceptable” in an interview with CBS News.
“It means that President Putin is continuing to escalate this war in a manner that is totally unacceptable and we have to continue to stem his actions in the strongest possible way,” she said.
