Vladimir Putin refuses to accept Donald Trump's ultimatum for a ceasefire, continuing to aim for the complete capture of four Ukrainian regions.

Kremlin sources say Putin doesn't want to anger Trump, but will press ahead with war plans to capture the regions of Donetsk, Luhansk, Zaporozhe and Herson. Trump has threatened new sanctions and tariffs, but Putin is skeptical they will have a significant impact. Peace talks are difficult and Russia's demands, including Ukraine's withdrawal from occupied regions, are being rejected by Kiev. Trump, who has criticized Putin's actions, wants a truce, but the Kremlin has not offered a clear response.
