Cladding on Grenfell Tower was used on other buildings around the world that have been hit by fires, according to BBC Newsnight.

High-rise buildings in France, the UAE and Australia that had similar cladding had fires that spread.

Rydon, which completed the renovations, said the work on Grenfell Tower met all fire regulations.

The Department for Communities and Local Government has "dragged its feet" since the 2009 Lakanal House tower block fire, in Camberwell, south-east London, according to Prof Kurt Barling of Middlesex University London.

He told BBC Breakfast: "Four years on from a really important inquest into a really tragic fire in which six people lost their lives, the same questions are being asked.

"People are right to ask why has nothing been done substantially to prevent this happening again.

"Clearly this building has failed, and the systems put in place to prevent fire in tower blocks has failed too."

• 12 people are known to have died, and the death toll is expected to rise
• Many people remain missing
• 34 patients remain in hospital, with 18 in critical care
• Families are being looked after locally in makeshift rescue centres

BBC Radio 4

The BBC's Andy Moore is at the Westway Sports and Fitness Centre, which has been set up as a refuge for Grenfell Tower residents and those evacuated from homes nearby.

He tells BBC Radio 4 the fire is now largely out, though there is still some smoke emerging from the block. The fire service have not yet managed to search the entire building. It is feared that the recovery of bodies will be a long, complicated process.

Bed rolls for those affected have been set up on the sports hall floor at the Westway centre.

Andy says: "The Red Cross have a presence outside, and the pile of donations is growing. People have given clothes, water, toiletries.

"We know the fire service say they managed to help to safety some 70 people. We don't know the numbers missing and unaccounted for. We're aware of entire families at the moment who are missing."

More than £1m has been raised for people affected.

One appeal on JustGiving has raised at least £286,000 while another has reached more than £430,000.

The London Evening Standard launched an appeal on Wednesday, which has raised more than £282,000.

At the scene of the fire, people have been writing messages of condolence on a wall near the tower block.

BBC News Channel

Bhupinder Singh, a volunteer, told the BBC he was one of a number of people looking after donations - including clothes, pushchairs and cots - piled up in a car park close to the fire overnight. He said other donation spots and evacuations centres were already full.

BBC senior reporter Sarah Corker, who remains at the scene, said firefighters have been working through the night to dampen the fire.

She said crews using an aerial platform were going "floor by floor" shining lights into the building.

Flames could still be seen inside some flats - more than 24 hours after the blaze began - she added.

Matt Wrack, the Fire Brigades Union chief, said serious questions need answering in the wake of the blaze. He said residents of the north Kensington block "have the right" to ask questions about whether alterations to the cladding compromised the safety of the building.

Tuesday night's edition of BBC Two's Newsnight looked into reasons why this fire spread so rapidly around the building and focused firmly on the cladding on the outside of the tower block

The programme said it had learned that part of the cladding on Grenfell Tower was made from materials that have been linked to fires in other countries.

The programme's policy editor Chris Cook said the outer skin of the cladding - added during a refurbishment in 2015 - consisted of two aluminium sheets around a polyethylene - or plastic - core.

"This type of cladding has been cited as enabling the spread of high-rise fires in France, the United Arab Emirates and Australia," he said.

Experts told Newsnight they believe cladding with a mineral core is more fireproof than products with a plastic core.

The manufacturer of the cladding used in Grenfell Tower - sold under the brand Reynobond - offers both types.

Rydon, the company that led the refurbishment, said: "The project met all required building regulations".

Thursday's newspapers all carry extensive coverage of the fire. The papers all have dramatic images of Grenfell Tower ablaze on their front pages. Some ask questions about how such a tragedy could happen.

Officials say emergency accommodation is tonight being provided to 44 households affected by the fire. Families with young children, elderly residents and those who are vulnerable are being given "immediate priority".

People unable to return to their homes have been offered a place to stay at the nearby Westway Sports Centre.

The Guardian

A doctor from King's College hospital in south London has told the Guardian newspaper, external how he was woken up by an automated message about a major incident.

"My first fear was: is this another terror incident? Oh God, what’s happened this time?" Dr Malcolm Tunnicliff, clinical director for emergency and acute care, said.

He described how staff dealt with casualties from the fire: "The injured were a mixture of children and adults, both men and women, ranging in age from four or five to middle age.

"A number of the casualties were very unwell. All had injuries caused by smoke inhalation, some of which were very serious, and also carbon monoxide poisoning."

He told the newspaper he was "very proud" of staff who had "stepped up to the mark for the third major incident in three months".
