Earlier this month, Trump set a 50-day deadline for Moscow to agree to a ceasefire, threatening fresh sanctions and tariffs if it failed to do so. Trump also announced new military support for Kyiv, with a particular focus on strengthening Ukraine's anti-drone and anti-missile defenses.

Donald Trump has presented a new, shorter deadline for Russia to agree to a ceasefire over the war in Ukraine of "ten or 12 days" from Monday. The US president said there was "no reason" in waiting any longer as no progress towards peace had been made.

Russia and Ukraine discussed further prisoner swaps on Wednesday at a brief session of peace talks in Istanbul, but the sides remained far apart on ceasefire terms and a possible meeting of their leaders.
