Fresh Ukrainian troops are being redeployed to the heavily threatened front-line regions of Pokrovsk and Kurakhove, while Ukraine's president said he could agree to a ceasefire if NATO agrees to protect areas under Ukrainian control.

President Volodymyr Zelensky has suggested that the parts of Ukraine under his control could be taken "under the Nato umbrella" to try and stop the "hot phase" of the war.

Ukraine President Volodymyr Zelensky suggested he would accept a ceasefire with Russia that left parts of his country occupied in return for Nato security guarantees over the rest, the strongest signal yet that the Ukrainian leader is open to ending the war without regaining all territory.
