Evacuation of civilians from the Azovstal plant in Mariupol

Thanks to all for the help with translation, English captions updated. I don't know what's the source from this video, it was already edited like this. From the news: "Russian and DPR troops opened a humanitarian corridor for the safe evacuation of civilians. All released residents were evacuated to Bezymennoye in the DPR, where they were provided with shelter, food and medical assistance. Those evacuated by the DPR who wished to leave for areas controlled by the Kiev government were handed over to representatives of the UN and the Red Cross. Some say there may be still 300 people inside Azovstal." (Why??)
