Dramatic footage has emerged from China of at least one explosion at a chemical warehouse in China.

The video, filmed in Yichun, Jiangxi Province on Monday, shows bright flames and heavy black smoke rising from the factory into the sky.

One of the explosions was reportedly so large, that the glass of the windows in a factory 500 metres away was smashed.

According to local reports, it took 120 firefighters and emergency workers 11 hours to extinguish the blaze.

There were no reported casualties.
