MOSCOW (Reuters) - The Kremlin said on Monday that Kiev had sent Russia mixed signals about the war in eastern Ukraine despite agreeing to a peace plan and that no progress had been made on organising an international summit aimed at finding a resolution.

In a breakthrough last month, Ukrainian, Russian and separatist negotiators had agreed that Kiev would grant the territory controlled by the separatists autonomy and hold local elections, prompting protests at home by critics who accused Ukrainian President Volodymyr Zelenskiy of yielding to Moscow.

The breakthrough appeared to open the way to a possible summit between Russia, Ukraine, France and Germany known as the Normandy Four.

“There’s a lot that isn’t clear at the moment,” Kremlin aide Yuri Ushakov told reporters at a briefing.
