Russian President Vladimir Putin stepped up his threats against Western countries Thursday, warning that if they send their own troops into Ukraine they risk global nuclear war.

Putin issued the threat at the top of his annual state of the nation address, ahead of a presidential election next month that he is certain to win.

Macron’s suggestion was swiftly rejected by the United States and others, but Putin said that such a development would risk a wider war with potentially apocalyptic consequences.
