None of opened humanitarian corridors in Ukraine de facto worked - Russian presidential aide

MOSCOW. March 7 (Interfax) - The humanitarian corridors on the territory of Ukraine did not work to the full extent as nationalists were obstructing evacuation, Russian presidential aide Vladimir Medinsky said.

"Unfortunately, none of them [humanitarian corridors] fully worked as of now. Our side was monitoring each of these corridors using drones - nationalists were preventing civilians from leaving the city," Medinsky told Rossiya 24 (VGTRK) television.
