The EU and Britain announced new sanctions against Russia on Tuesday without waiting for the United States to join them, a day after President Donald Trump spoke to Vladimir Putin without winning a promise for a ceasefire in Ukraine.

The talk comes as Russia and Ukraine failed to reach any sort of deal when they held their first face-to-face talks in three years in Istanbul on Friday. Trump had offered to attend the talks in Turkey if Putin would be there, however, the Russian president declined to go.

European capitals have launched a flurry of diplomatic efforts to maintain pressure on Russia and convince US President Donald Trump’s administration not to walk away from Ukraine peace talks. Multiple calls and meetings took place on Tuesday between European and Ukrainian leaders and senior security officials following Monday’s phone call between Trump and Vladimir Putin in which the US president signalled he would leave Russia and Ukraine to settle among themselves the terms for ending the war.
