Ukrainian officials, security monitors and Kyiv's foreign backers had warned on Wednesday that Moscow's decision to withdraw from a Ukrainian-Russian ceasefire control group could worsen the fighting in eastern Ukraine, as reported by Reuters.

Macron and Merkel said in their statement there was no alternative to an exclusively peaceful settlement and called for a return of the Russian officers to the Joint Centre for Control and Coordination. Russia had accused the Ukrainian side of obstructing their work and limiting access to the front line.
