Russia warns UK is 'playing with fire' over Salisbury nerve agent attack

Russia has warned Britain is "playing with fire and will be sorry" over the Salisbury poisoning as it emerged Yulia Skripal's strength is "growing daily".

The two countries referenced British dramas and the Nazis as they traded jibes at the United Nations, with the UK arguing that doubt should not be cast on the likelihood of Russian responsibility for the Novichok nerve agent attack and that British actions "stand up to any scrutiny".
