SHANGHAI: Seven people were killed on Thursday (May 16) when a building undergoing renovation collapsed in China's financial hub of Shanghai.
The accident happened at around 11.30am in Shanghai's Changning district. The roof of the two-storey building caved in on construction workers, trapping them under the rubble.
About 21 people have been pulled out of the debris and rushed to hospital, according to official Xinhua news agency.
A verified account run by China's emergency ministry showed pictures of rescue personnel pulling bloodied and dust-coated workers out from amid piles of rubble, toppled concrete pillars and shattered wooden beams.
The low-rise building had previously been used as a dealership for Mercedes-Benz cars, the fire rescue bureau said.
Chinese media reports said it was being redeveloped as a mixed-use arts and innovation site.
A local resident told AFP she was taking a nap when her bed suddenly began shaking, as if in an earthquake. She then heard a loud bang.
"I thought it was an explosion at first," said the woman, who declined to give her name or to comment further.
The bureau did not announce any deaths nor provide details on injuries. Authorities quickly sealed off the area with a huge security presence, preventing journalists from getting close.
The city government did not say why the building collapsed.
Chinese media reports said the structure was around 3,000 square metres in area. Aerial pictures on social media indicated that the roof of about half of the building collapsed.
China has seen numerous building collapses in recent years, typically blamed on low-quality construction and the flouting of safety rules.
At least 20 people were killed in 2016 when a series of crudely-constructed multi-storey buildings that were packed with migrant workers collapsed in the eastern city of Wenzhou.
