Watch the moment 15 tower blocks get demolished simultaneously in China

This is the moment 15 unfinished buildings were demolished at the same time in a China.

The spectacular video, filmed in the city of Kunming in Yunnan Province, shows the tower blocks, which had stood for seven years, come crashing down at the same time.

Authorities decided to take action because the buildings had been abandoned for a long time and the basements were submerged in rain water.

The total demolition area, measured by floorspace and number of buildings, is reportedly the largest for a one-time demolition in China.
