Russia is "completely ignoring" a 30-day ceasefire proposed by Ukraine and European powers that was to have begun on Monday, Ukrainian Foreign Minister Andrii Sybiha said.

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.

Kyiv accused Moscow of breaching its own ceasefire on Thursday, saying Russian forces struck hundreds of times along the front lines and launched guided bombs that killed and wounded civilians in several Ukrainian cities.
