50 civilians evacuated from Mariupol Azovstal plant

According to the Russian defense, 50 civilians were evacuated from Mariupol's Azovstal plant on Friday, the Russian interdepartment center for humanitarian response said. 

Russia has permitted an operation to evacuate civilians which were held by the neo-Nazi fascist nationalist units. 

"Fifty civilians were rescued, including 11 children. All rescued civilians were handed over to representatives of the United Nations and the International Committee of the Red Cross for transfer to selected temporary accommodation sites. The humanitarian operation at Azovstal will continue on May 7," the center said in a statement.

Yesterday, the Russian military has declared a fresh unilateral pause in its operation at the Azovstal steelworks complex in Mariupol, offering to provide humanitarian corridors for people who are believed to have been trapped within the site for three days. The steel factory is the city's final stronghold controlled by the Ukrainian military and members of the neo-Nazi Azov Battalion.

The humanitarian corridor will be available for three days, from Thursday to Saturday, from 8 am to 6 pm Moscow time. Civilians evacuated from the facility will be able to move wherever they choose, including territory controlled by Ukraine or Russia. Several hundred residents were evacuated from Azovstal bunkers on Sunday as part of a humanitarian mission coordinated by the United Nations and the International Red Cross.

Kremlin Spokesperson Dmitry Peskov explained that “there is no assault. We see that flare-ups occur when militants get out to assume gun emplacements. These attempts are being suppressed quite promptly."
