Vladimir Putin rejected Donald Trump’s proposal for an immediate ceasefire in Ukraine after a “frank” phone call between the two presidents.

Instead, the Russian leader agreed to a 30-day pause in attacks on energy and infrastructure and to hold further talks on stopping hostilities in the Black Sea.

Putin also demanded that Ukraine not rearm or mobilise during the partial truce and called for a “complete cessation” of Western military and intelligence support to Kyiv.

France and Germany vowed on Tuesday night to continue supplying weapons to Kyiv, raising doubts over whether a deal on Putin’s terms can hold. Downing Street has not yet addressed whether Britain will follow suit.

Shortly after the Trump-Putin call, explosions rang out and air sirens sounded over Kyiv, where authorities urged people to take cover from the threat of Russian aerial attacks.

Volodymyr Zelensky said that the phone call showed the Kremlin was “not ready” to end the war and that its ultimate aim in talks on halting the conflict was to “weaken” his country.
