Ukrainian journalist confronts Boris Johnson in Warsaw press conference

A tearful Ukrainian journalist who fled over the border confronted Boris Johnson with demands for Britain to enforce a no-fly zone over her country to protect civilians from Russian bombs. Daria Kaleniuk emotionally argued to the Prime Minister at a press conference in Warsaw, Poland, on Tuesday that allies from the Nato defence alliance are wrong to rule out the step out of a fear of provoking a nuclear war with Vladimir Putin.
