London police say 58 people who were in Grenfell Tower are still missing and assumed to be dead. Authorities Saturday said that this number, which was based on reports from the public, may rise.

UPDATE June 17, 8:59 a.m. EST: Queen Elizabeth II marked a minute of silence Saturday for victims of the London high-rise inferno that killed at least 30 people.
Firefighters are still searching for more bodies.
Much of the public is angry over a lack of questions about how the blaze spread so quickly.
Several reports claim that contractors installed a cheaper, less flame-resistant type of exterior paneling in a renovation of Grenfell Tower that ended in May 2016.
We are equally determined, without fear or favor, to support all those rebuilding lives so horribly affected by injury and loss.
The Queen also issued a somber message on her birthday following her visit to the site of the fire:
"Today is traditionally a day of celebration," Queen Elizabeth said in a statement. "This year, however, it is difficult to escape a very somber national mood. In recent months, the country has witnessed a succession of terrible tragedies."
"Put to the test, the United Kingdom has been resolute in the face of adversity," she wrote.

ORIGINAL STORY: At least six people are dead and more than 50 have been hospitalized after a fire engulfed a residential tower in London overnight, the BBC reported.
Firefighters rescued "large numbers" of people from Grenfell Tower in north Kensington but London Mayor Sadiq Khan said many people are unaccounted for.
The 24-story building is still on fire and appears at risk of collapsing.
Witnesses described a horrific scene, with people trapped in the burning building screaming for help for themselves and their children. Some reported seeing lights -- perhaps cell phones -- flashing near the top of the building as trapped residents, some holding children, stood by their windows.

Some were quick to speculate that the blaze was "no accident."
Khan assured Londoners they'll get "all the answers" on the cause of the fire.
Smoke from the fire hovered over London early Wednesday.
