Hong Kong: Firefighters search for missing in tower blocks fire

Firefighters are still searching for hundreds of missing people after a massive fire tore through multiple high-rise residential buildings in Hong Kong.

At least 83 people died in the blaze - the city's deadliest in more than 70 years - at Wang Fuk Court's complex, which is home to thousands.

The tower blocks had been undergoing extensive renovations - and while the exact cause for the fire is unclear, police say materials on the outside of the buildings may have facilitated its spread.

 The fire began on the bamboo scaffolding outside one of the buildings. This type of scaffolding, made from bamboo poles used by workers during repairs, burns very easily. Once the scaffolding caught fire, the flames quickly spread up the structure and into the building, and then to nearby towers.
