Ukraine's air force says Russia launched more than 100 Shahed and decoy drones at Ukraine in nighttime attacks.

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.

Three-day ceasefire in Ukraine that was unilaterally declared by Russian President Vladimir Putin last month was set to come into effect at 5 p.m. ET on Wednesday (midnight Moscow time), as Russia prepares to mark the anniversary of its World War II Victory Day on Friday.

Moscow had discussed reviving the gas pipeline in talks with President Trump on improving economic ties with Washington.

The weapon is made with a model aircraft engine available for approximately $16,000, according to the Ukrainian Main Intelligence Directorate.

By the time Vladimir Putin spoke in a televised address in the early hours of May 11th—bluntly ignoring the ultimatum while offering direct negotiations laden with multiple strings—the moment had lost all clarity.

The ultimatum from Berlin comes as Ukraine said Russia was still carrying out attacks along the front line, despite a ceasefire proposal agreed on the weekend among Kyiv's allies for a 30-day ceasefire to start Monday. The Kremlin said such an ultimatum "is unacceptable for Russia."
