A public inquiry into the 2017 fire at London's Grenfell Tower, which killed 72 people, began to zero in Monday on how the densely populated social housing block was allowed to become a tinder box and who was to blame.
The 23-story tower, owned by the wealthy west London borough of Kensington and Chelsea, was destroyed on the night of June 14, 2017, in Britain's worst fire in a residential building since World War II.
The disaster shocked the nation, prompting an outpouring of grief as well as soul-searching over allegations by survivors that neglect of their ethnically mixed, largely low-income community had played a part.
