At least 12 people are dead and dozens injured after a massive fire rapidly tore through a 24-story apartment building in west London in the early hours of Wednesday, police said.
All 24 floors of Grenfell Tower in North Kensington were swiftly engulfed, trapping residents in their homes and reportedly forcing some to jump to escape the flames. London's fire chief, Dany Cotton, said the blaze was "unprecedented" in her 29 years of service.
Residents had reported concerns about fire safety in recent years, and questions were raised about whether a recent refurbishment of the building, in which exterior cladding was installed, contributed to the rapid spread of the fire.
Firefighters continued to search the building for survivors.
