Europe is closer to war on the continent than it has been for 70 years, a UK minister has said.
He said Moscow had prepared the “unglamorous stuff” to support an attack – such as fuel and medical supplies – that would not be needed if the build-up on the Ukrainian border were only about “winning leverage in diplomacy”.

Ukrainian president Volodymyr Zelensky has invited Joe Biden to visit Kiev to show solidarity. He said he had not seen US intelligence on an invasion.
German chancellor Olaf Scholz will today meet Mr Zelensky in Kiev before heading to Moscow on Tuesday to meet Vladimir Putin.
