Watch | 27-storey building in China turns into ash in 15 seconds

Dramatic footage has emerged from China of the moment a 118-metre-tall building was demolished. The building had never been put into use for a day since it was completed in 1999. The video, captured in Xi'an, Shaanxi Province on Sunday morning, shows the building disappearing into ash and rubble within 15 seconds following the explosions. The 27-storey building is so far the highest that has been demolished in mainland China.
