LONDON — Grenfell Tower residents said they had warned about fire hazards for years before their London public housing project became a 24-story cinder. On Friday, they stormed the local government council, accusing officials first of ignoring them and then of leaving them without financial assistance and lodging, or even a rough accounting of their missing loved ones.

With scores of residents still unaccounted for since the early Wednesday fire, frustrated survivors demanded from government officials help and a roster — or at least the number — of tower residents.

Prime Minister Theresa May and Mayor Sadiq Khan were heckled on separate visits with survivors. The queen and Prince William, upon leaving a relief center for the victims, were subjected to calls of “What about the children?”
