Children tossed from windows in London high-rise blaze

People leave donations near the burning 24 storey residential Grenfell Tower block in Latimer Road, West London.

Some people were trapped in the fire, with residents desperately shouting for help from windows on upper floors as the fire spread, some British media reported.

London's Metropolitan Police said a number of people were being treated for a range of injuries, but did not provide more specifics. "Many others are receiving medical care".

"All our warnings fell on deaf ears and we predicted that a catastrophe like this was inevitable", the group said after the fire broke out.

London Fire Commissioner Dany Cotton confirmed "a number of fatalities" from the inferno which broke out just before 1am United Kingdom time and burned upwards from the second floor of the tower, but she declined to speculate on a cause of the fire.

"The flames, I have never seen anything like it".

A local residents association had previously warned it was anxious about the risk of a serious fire in the block.

The London Fire Brigade has this morning confirmed there have been a number of fatalities.

Built in the 1970s, the housing block was recently upgraded at a cost of 10 million pounds ($12.8 million), with work finishing in May 2016, according to the local council.

Children were among those begging to be saved as families tried to escape the engulfed 24-storey block of flats in Ladbroke Grove, West London.

Steve Apter, director of safety and assurance at London Fire Brigade, said: "I can confirm I have had firefighters manage to get through particularly arduous conditions up to the top floor".

London Fire Brigade Assistant Commissioner Steve Apter said "almost all" of the building had been searched but there were "still pockets of fire yet to be extinguished in places particularly hard to reach".

"We saw the people screaming for help", Ms Boutrig said.

A newsletter a year ago advised residents that if there was a fire they should initially stay in their homes.

A Malaysian family residing in London has opened its doors to those affected by the fire that engulfed Grenfell Tower in North Kensington, London.

A blog post from Grenfell Action Group in November said "only a catastrophic event" would expose the concerns residents had.

Firefighters at the scene of Grenfell Tower fire.

Authorities say 65 people were rescued from the blaze.

Helicopters hovered overhead. Exhausted firefighters sprawled on the pavement just inside the police cordon, drinking water from plastic bottles.

Tia Abrahams, who lives close to the scene, got there before the fire brigade.

"The flames - I have never seen anything like it, it just reminded me of 9/11", said Muna Ali, 45.

He said he suspects the fire sprinkler system "was out of service or there was a malfunction at the time" based on how quickly the fire spread. In all, five people were taken to area hospitals, including the suspect, Alexandria police said.

"As the insurance provider for Royal Borough of Kensington and Chelsea, Protector Forsikring ASA is involved in the tragic fire in Grenfell Tower".

At least six people are dead and dozens of others have been left injured.
