Victims grieve tower's demolition years after deadly Grenfell blaze

Hamid Ali Jafari says he feels his father's presence every time he walks or drives past London's Grenfell Tower, where the 82-year-old died in a devastating blaze more than seven years ago. He's one of many grieving the government's decision, on engineers' advice, to demolish the remnants of the high-rise building. Fiona Jones reports.
