Demonstrators are watched by security personnel on a staircase after they entered Kensington Town Hall, during a protest following the fire that destroyed The Grenfell Tower block, in north Kensington, West London, Britain June 16, 2017.
London police said Saturday that the death toll from the inferno at the Grenfell Tower in west London had risen to 58.
Commander Cundy said in a statement: "It is really important that we are clear about the scale of the challenge facing us as our teams search Grenfell Tower to recover those people still inside and return them to their loved ones".
Metropolitan Police Commander Stuart Cundy later clarified that the number of people confirmed dead is 30, but another 28 remain missing and are presumed dead. A new sign was put up, removing that detail. British health authorities say that 19 patients are still being treated at four London hospitals.
Rescue personnel have had difficulty reaching the top floors of the charred, 24-story tower.
Hundreds have been left homeless by the blaze, and pressure is growing for the government to act fast.
The Home Office said late Saturday night it will make arrangements for the family of Mohammad Alhajali to "travel to the United Kingdom in these terribly sad circumstances".
May, criticized in the first few days after the blaze for failing to meet with victims, says the public inquiry looking into the tragedy will report directly to her.
The tower's flammable cladding is widely believed to be the main reason for the rapid spread of the blaze. "People have lost their lives and others have lost everything, all their possessions, their home and everything".
Matthew Parris, a columnist and former Conservative lawmaker, said May's response to the fire had shown a lack of judgment which made her unsuitable to be prime minister.
"Finally, I would like to repeat what I have said before which is that my heart goes out, those of my colleagues, those of the wider emergency services, the community here, Londoners, and indeed everybody across this nation".
"It will go to establish the answers of what happened in the fire and how it spread; it will look at the building itself; it will look at the refurbishment as well".
Earlier, Londoners confronted and shouted at a Tory cabinet minister at the scene of the fire, while Ms May's chief of staff fled reporters asking why he had failed to undertake a called-for safety review.
Londoners and others have also donated huge amounts of food, water and clothing, and shelter, to survivors.
British officials have announced a nationwide minute of silence to honor the victims on Monday morning. British media have reported that contractors installed a cheaper, less flame-resistant type of exterior paneling on the 24-story tower in a renovation that was completed just previous year.
He also said that five people who had been reported missing after the incident have been found safe and well.
The queen marked her official birthday Saturday by saying Britain remains "resolute in the face of adversity" after the horrendous fire and recent extremist attacks in London and Manchester.
The 91-year-old monarch said it is "difficult to escape a very somber mood" on what is normally a day of celebration.
The Government admitted it may be necessary to push some residents out across the capital, despite Communities Secretary Sajid Javid having repeated the promise to keep people local hours earlier.
