US President Donald Trump has said he will slash the 50-day deadline he gave for Russia’s Vladimir Putin to reach a ceasefire with Ukraine by weeks, to just “10 or 12 days” from now.

During his visit to the U.K. on Monday, President Donald Trump expressed further frustration with Russian President Vladimir Putin.

Russia launched yet another attack on Ukraine overnight, with more than 300 drones and seven missiles, according to Ukraine's air force. While most of the barrage was intercepted, the relentless attacks prompted President Trump to give his Russian counterpart an ultimatum.

President Trump has shortened his deadline for Putin to end the war in Ukraine, now demanding action within 10-12 days and threatening severe tariffs. Medvedev responded sharply, calling Trump's ultimatum a dangerous escalation towards war,

The U.S. president said he is “very disappointed” in Russia’s leader.

President Donald Trump said he's giving Vladimir Putin 10 to 12 more days to reach a deal to end the Ukraine war. Otherwise, the president said Russia could face new sanctions and secondary tariffs targeting its trading partners.

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.

Ukrainian Foreign Minister Andrii Sybiha has described US President Donald Trump’s decision to shorten the deadline for Kremlin ruler Vladimir Putin to achieve peace as a "realistic and firm" position.

Putin's spokesperson, Dmitry Peskov, says the Kremlin supports diplomacy in resolving the war. At the same time, Moscow complained that Ukraine had allegedly rejected the possibility of dialogue. Peskov was asked how relations between Russia and Ukraine will be built after the war is over.
