Three evacuation corridors have been announced in Ukraine

Vereschuk said it is a corridor for evacuation of Marioupolis residents and sending humanitarian aid to Berdyansk, a route for sending humanitarian aid and evacuation from Melitopol and one for a column of personal vehicles from Enerhodar to Zaporizija.

The bus and truck convoys with humanitarian aid have already left Zaporizhja. We demand that the invading forces respect their commitments and allow humanitarian columns through roadblocks”, she said in a video message today.

Vereshchuk said the Russian delegation to yesterday's talks between Russian and Ukrainian teams in Istanbul received proposals from the Ukrainian side to organise evacuation corridors for regions affected by fighting, including Kharkiv, Kherson, Chernihiv, Summy, Zaporizija, Donnetsk region, Luhansk and Mykolaiv.

Vereshchuk's announcement came two days after the city's besieged mayor of Marioupol said evacuation corridors had largely fallen under Russian control, as weeks of shelling killed an unknown number of civilians and forced hundreds of thousands of residents to flee their homes.

Not everything is in our power,” Mayor Vadym Boichenko said in a live TV interview. Unfortunately, today we are in the hands of the invaders.

Boichenko called for a complete evacuation of Marioupolis's remaining population, which was home to more than 400,000 people before Russia began its invasion in Ukraine on 24 February.

Ukrainian officials have said Russian forces have prevented evacuation convoys from approaching or leaving the southern port city safely, CNN broadcast.
