Fire engulfed a 24-storey housing block in central London in the early hours on Wednesday, killing at least six people and injuring 74 others in an inferno that trapped residents as they slept.
Some residents screamed for help from behind upper floor windows, some tried to throw children to safety, as flames raced through the high-rise Grenfell Tower block of apartments in the north Kensington area after taking hold just before 1am.
โWe could see a lot of children and parents screaming for โHelp! Help! Help!โ and putting their hands on the window and asking to help them,โ Amina Sharif, a witness, told Reuters.
โWe could do nothing and we could see the stuff on the side was falling off, collapsing. We were just standing screaming and they were screaming.โ
Another witness, Saimar Lleshi, saw people tying together sheets in an attempt to escape.
โI saw three people putting sheets together to climb down, but no one climbed down. I donโt know what happened to them.โ
โEven when the lights went off, people were waving with white shirts to be seen,โ Lleshi said.
More than 200 firefighters, backed up by 40 fire engines, fought for hours to try to bring the blaze, one of the biggest seen in central London in memory, under control.
By mid-day, London police said six people had been killed and they cautioned the death toll was likely to rise.
Police Commander Stuart Cundy said a โrecovery operationโ could take some time and there could be people in the building who are unaccounted for, though he would not be drawn on a figure.
Fire-fighting crews still had to reach the top four floors of the building where several hundred people live in 130 apartments.
The cause of the inferno, which left the tower block a charred, smoking shell, was not immediately known.
The block had recently undergone an ยฃ8.7 million refurbishment of the exterior, which included new external cladding and replacement windows.
Black smoke billowed high into the air for hours after the blaze broke out. Residents rushed to escape through smoke-filled corridors after being woken up by the smell of burning.
London Fire Brigade said the fire engulfed all floors from the second to the top of the 24-storey block. There were reports that some residents leapt out of windows to escape the flames.
One woman lost two of her six children as she tried to escape from the block, one witness said.
โI spoke to a lady that lives on the 21st floor. She has got six kids. She left with all six of them. When she got downstairs there was only four of them with her. She is now breaking her heart,โ Michael Paramasivan, a block resident, told BBC radio.
Other witnesses spoke of children, including a baby being thrown to safety, from windows high up.
Tamara, one witness, told the BBC: โThereโs people, like, throwing their kids out: โJust save my children, just save my children!’โ.
โIn my 29 years of being a fire fighter, I have never ever seen anything of this scale,โ London Fire Brigade Commissioner Dany Cotton told reporters.
London mayor Sadiq Khan said the fire raised questions over safety of high-rise blocks like Grenfell Tower. The BBC reported that a political deal between the government of Prime Minister Theresa May and a small Northern Irish party could be delayed because of the aftermath of the fire.
More than 12 hours after the fire broke out, the building was still smouldering, though the building was not in danger of collapse.
Firefighters rescued large numbers of people โ some of them in their pyjamas โ from the 43-year-old block, a low rent housing estate which overlooks up-scale parts of the Kensington area.
Burning debris cascaded from the blazing building.
โThere was bits of building falling off all around me, I scalded my shin on a hot piece of metal that had fallen off the building,โ said Jodie Martin, who lives close to the building and had gone to the scene to try to help.
โI was just screaming at people: โGet out, get outโ and they were screaming back at me: โWe canโt, the corridors are full of smokeโ,โ he told BBC Radio.
RESIDENTSโ CONCERN
Residents said they had warned repeatedly over fire safety in the block.
Londonโs mayor Khan said questions needed to be answered over the safety of tower blocks after some residents said they had been advised they should stay in their flats in the event of a fire.
A local residents association had previously warned it was worried about the risk of a serious fire in the block.
โThese questions are really important questions that need to be answered,โ Khan said.
โWhat we canโt have is a situation where peopleโs safety is put at risk because of bad advice being given or if it is the case, as has been alleged, of tower blocks not being properly serviced or maintained.โ
The local council of Kensington and Chelsea, which owns the block, said it was focusing on supporting the rescue and relief operation. It said the causes of the fire would be fully investigated.
Police closed the A40, a major road leading out of west London, while some parts of Londonโs underground train network were closed as a precaution.
