The death toll from a massive fire in a high-rise residential complex in Hong Kong has risen to 75, with about 70 people injured and some 200 still unaccounted for more than a day later, local authorities said Thursday, Kyodo News reported.

Three men have been arrested on suspicion of manslaughter in connection with the fire that broke out in the northern Tai Po district on Wednesday afternoon. The blaze rapidly enveloped seven of the eight towers in the Wang Fuk Court housing complex.
