An eyewitness video has emerged capturing the moment a deadly landslide hit 33 buildings in Shenzhen in south China.

The footage, filmed on a mobile phone, shows plumes of dust and ashes rising into the air as buildings collapse in an industrial park of the city in Guangdong Province.

Seven people have so far been pulled out of the rubble but more than 91 are still missing. Over 900 residents have been affected and more than 3,000 people, including firemen, police and health workers, are working at the scene, according to Chinese news agency Xinhua.

Chinese President Xi Jinping and Premier Li Keqiang ordered immediate rescue efforts following the disaster.

The Ministry of Land Resources blamed the landslide on a man-made mountain of dirt, cement chunks and other construction waste that had been piled up against a hill over the past two years. Heavy rains in the region had saturated the soil, making it increasingly unstable and ultimately causing it to collapse with massive force
