The new number may change as the investigation continues, Cundy said. He said that the search and recovery operation in the 24-story Grenfell Tower continues.

London police said on Monday that 79 people were now believed to have died in the high-rise apartment building fire.

Police Commander Stuart Cundy gave the new figure during a statement outside Scotland Yard, saying it includes both people who were confirmed dead and others who are missing and presumed dead. It is an increase from the previous number of 58.

The new number may change as the investigation continues, Cundy said. He said that the search and recovery operation in the 24-story Grenfell Tower continues, he said, adding that it has been incredibly distressing for families.

“It’s hard to describe the devastation the fire has caused,” Cundy said, fighting back tears as he spoke.

Cundy said that authorities were continuing to investigate whether any crimes had been committed in the fire. Two British officials said Sunday that new exterior cladding used in a renovation of the high—rise may have been banned under U.K. building regulations.
