Ukrainian President Volodymyr Zelensky says he is pleased to see that Russia is engaging with finding an end to the war, but there must be a ceasefire before peace talks can start.

Russia resumed mass drone attacks in Ukraine early on Sunday, after its self-declared three-day pause expired.

The announcement was made by leaders of Britain, France, Germany, Poland and Ukraine after a meeting in Kyiv, and a phone call with President Trump.
