An onlooker to the London Grenfell Tower fire captured footage of the raging fire and children, trapped in the building, repeatedly screaming for help.
The fire of the 27-storey building left six dead and dozens missing, as firefighters could only get up to the 20th floor during the rescue operation. Five hospitals across London are treating 74 people, but the casualty and fatality numbers are expected to rise.
BBC interviewee, Tamara, said, "There wer people just throwing their kids out saying 'Save my children.' Within another 15 minutes the whole thing was up in flames and there were still people at their windows shouting 'Help me.'
