The European Council's president talks about Ukraine's security. "Now is the time to accelerate our practical work to put in place a guarantee similar to NATO's Article 5 with continued United States engagement," Antonio Costa said. But Ukraine's military has to be the "first line of defence", he added. Costa said the main security guarantee - a key topic of discussion since Donald Trump's talks with Vladimir Putin on Friday - must be for Ukraine to have armed forces capable of defending its sovereignty. He's also touched on the need to advance on trilateral talks - which would involve Trump, Putin and Volodymyr Zelenskyy - and on Ukraine's EU membership.
