Fire of a new CCTV skyscraper in Beijing

Measuring 44 heels, 159 meters high and 241-room hotel rooms, the Mandarin Oriental skyscraper burned down in downtown Beijing.
The luxury hotel included in the complex of the new headquarters of Chinese television burned down completely, the cause of the tragedy were probably fireworks.
The skyscraper, built for over 6 years, has not yet been put into use, so there probably was nobody inside.
