A government-ordered inquiry into the London tower fire that killed at least 80 people opened Thursday with a minute of silence for the victims — and with its leader acknowledging that survivors feel a "great sense of anger and betrayal." Retired judge Martin Moore-Bick said he hoped his investigation would "provide a small measure of solace" by discovering how such a disaster could occur in 21st-century London, and preventing it happening again. The June 14 blaze began in a refrigerator in an apartment at Grenfell Tower before racing through the 24-story building. One aspect of the investigation will be the role of combustible aluminum cladding installed during a refurbishment to the 1970s tower block. Emergency safety checks have uncovered scores of other buildings across Britain with similar cladding.
