Firefighters were still dousing a devastating fire Thursday which ripped through a Hong Kong high-rise complex, killing at least 55 people and leaving hundreds missing according to authorities. The inferno — the financial hub’s worst in decades — took hold on Wednesday afternoon in an eight-building housing estate with 2,000 apartments and sent shockwaves through the city, which has some of the world’s most densely populated and tallest residential blocks. Police said early on Thursday they arrested three men in connection with the fire, after flammable materials left during maintenance work caused the blaze “to spread rapidly beyond control”.
