The foreign ministers of Ukraine's main European allies said on Monday they would redouble their aid to the country while considering new sanctions on Russia to force it to accept a ceasefire.

Europe's top diplomat Kaja Kallas urged Russia on Monday to show goodwill and agree on a ceasefire in Ukraine. She said "giving back Ukrainian children that have been deported to Russia" and "releasing prisoners of war" were examples of gestures Russia could make to show goodwill.

Europe is seeking to retain its leverage as President Donald Trump moves to strike a deal with Russia to stop the war in Ukraine. But some of Russia’s key demands — including sanctions relief and the end of military aid to Ukraine — require European buy-in.
