European leaders have urged Russia to agree to an unconditional 30-day ceasefire with Ukraine starting on Monday.
The call was issued at a meeting of the "coalition of the willing" in Kyiv. The leaders of France, Germany, the UK and Poland were hosted by Ukraine's Volodymyr Zelensky, while others joined remotely.
They made the announcement after discussing the plan by phone with US President Donald Trump - who initially mooted an unconditional ceasefire. The leaders threatened Russia with "massive" sanctions if it does not comply.
UK Prime Minister Sir Keir Starmer said the aim of the coalition of the willing was to show "that aggression will never prevail on our continent".
