US President Joe Biden has warned Russia against using nuclear weapons in Ukraine, saying it would be an “incredibly serious mistake”.
The Biden administration had earlier said Russia had given notice that it intended to stage routine drills of its nuclear capabilities while Ukraine’s nuclear energy operator claimed its neighbour was performing some secret work at Europe’s largest nuclear power plant.
“Let me just say: Russia would be making an incredibly serious mistake if it uses a tactical nuclear weapon,” Biden told reporters at the White House on Tuesday.
