Witnesses have told how they were woken by screaming in the early hours after a fire hit 27-storey Grenfell Tower in north Kensington.
Joanna O'Connor, a local resident, told Sky News: "At about 2am woken up by screaming, sirens and helicopters. We came outside and were confronted with the building that was completely engulfed in flames.
"It was a real shock and there were hundreds of people lining the streets, we could still hear screaming from the building and people were milling around in shock crying.
"One of our neighbours, her sister, husband and children were in the building, it was their neighbours' flat that caught fire. So it's very close to us, we've got neighbours whose families are in that building."
Local resident Tamara told BBC News: "Around 12.30/1am my mum called me and said there was a fire outside. By the time I got there the whole right side of the building was on fire, the whole thing was engulfed in flames.
"We could hear people screaming 'Help me' so me and my brother, with some other people who live in the area, ran over to the estate to where you could still get underneath it and there were people just throwing their kids out saying 'Save my children'.
"The fire crew, ambulance and police couldn't do anything, they couldn't get in, and they were just telling them to stay where they are, and we'll come and get you. But things quickly escalated beyond measure and they couldn't go back in and get them.
"Within another 15 minutes the whole thing was up in flames and there were still people at their windows shouting 'Help me'. You could see the fire going into their houses and engulfing the last room that they were in."
