Commander Stuart Cundy, a spokesman for London's Metropolitan Police, also cautioned there may have been people in the tower that police are not aware of, which would add to the death toll.
The fire ripped through the high-rise early Wednesday.
Panels of the armor-like "cladding" have become a popular facade on tall buildings worldwide, both for their sleek look and energy-saving virtues. Though cladding can be flame-resistant, the result can be deadly when it is not. "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, according to the Associated Press. He said that the search and recovery operation in the 24-story Grenfell Tower continues, and it has been incredibly distressing for families.
Another complicating factor is that much of the DNA material that would normally be used to help pinpoint victims - like toothbrushes or combs - were probably also incinerated in the blaze. "So that 58 would include that 30", he said.
Authorities are still investigating the fire. Its behavior strongly implicated the cladding, several fire safety experts said in interviews.
Cladding with pure plastic insulation costs less and insulates better than an alternative that incorporates fire-slowing minerals, experts said.
Not so for taller buildings.
"When the truth comes out about this tragedy, we may find that there is blood on the hands of a number of organizations", Lammy said.
Trade Minister Greg Hands said the government is carrying out an "urgent inspection" of the roughly 2,500 similar tower blocks across Britain to assess their safety. A 2007 casino fire in New Jersey was a wake-up call in the United States. I was expecting to hear lists of missing people, lists of people who had died, passed away. Exterior paneling helped the fire spread.
Grenfell Tower is located in a pocket of social deprivation within the borough of Kensington and Chelsea, one of Britain's wealthiest areas. I really hope it won't, but it may increase.
His family said in a statement that Alhajali "came to the United Kingdom because he had ambitions and aims for his life and for his family".
In November 2016 Mr Barwell replied to say his department had been looking at the regulations, and would make a statement "in due course".
Nearby the blackened shell of Grenfell Tower are the council-owned buildings of Markland House, Frinstead House and Whitstable House, and Ms Allison said she had "so many tips coming in that things there aren't tip top either". "You get a lot of fragmentation of bodies, charring of bones and sometimes all that's left is ash", said Peter Vanezis, a professor of forensic medical sciences at Queen Mary University in London. "Please, please give me some assurance that this isn't true, can someone from the powers-that-be come to visit us".
In some places, the issue is impossible to ignore. Gen. Rashid Thani al-Matrooshi acknowledged in April 2016.
"My understanding is that the cladding that was reported wasn't in accordance with United Kingdom building regulations", Hands told Sky News.
