It is the role of the USA to exert more pressure on Russia with a view to a ceasefire in Ukraine, said EU High Representative for Foreign Affairs Kaja Kallas at a meeting in the so-called Weimar+ format in Madrid. Ukraine had agreed to a ceasefire three weeks ago and there was still no response from Moscow. Vladimir Putin is playing his game and does not really want peace. Russia must now demonstrate goodwill and, for example, return deported Ukrainian children or release prisoners of war.
