World leaders condemn Putin
US President Joe Biden said Mr Putin had “chosen a premeditated war that will bring a catastrophic loss of life and human suffering”.
He said he would address Americans on Thursday about consequences Russia would face.
UKPrime Minister Boris Johnson said that the “hideous and barbaric venture by Vladimir Putin must end in failure”.
Addressing Russians, he said: “I cannot believe this is being done in your name, or that you really want the pariah status it will bring to the Putin regime.” He told Ukrainians that the UK was “on your side”.
Nato Secretary-General Jens Stoltenberg condemned Russia’s “reckless attack” saying it “puts at risk countless civilian lives”.
Europe was “facing its darkest hours since World War Two”, EU foreign policy chief Josep Borrell said.
However former US President Donald Trump says Mr Putin took advantage of American “weakness”.
He called Fox News to say that he didn’t believe that Putin “wanted to do this, initially”.
“I think he wanted to do something and negotiate, and it got worse and worse, and then he saw the weakness,” Trump said.
