President Vladimir Putin on Wednesday ordered Russia's first mobilisation since World War Two and backed a plan to annex swathes of Ukraine, warning the West he was not bluffing when he said he'd be ready to use nuclear weapons to defend Russia.
In the biggest escalation of the Ukraine war since Moscow's Feb. 24 invasion, Putin explicitly raised the spectre of a nuclear conflict, approved a plan to annex a chunk of Ukraine the size of Hungary, and called up 300,000 reservists.
