The death toll from Monday's construction site accident in central Beijing rose to six, official sources said on Tuesday.

The accident took place at about 10:10 PM Monday at the site of the No.4 building, part of the ongoing Xixi Project in Xidan, a business district in downtown Beijing. 

More than 40 workers were onsite mixing concrete when a steel scaffold collapsed, dropping some 20 meters, according to Liu Zhaoyuan, security chief with the Beijing Municipal Construction Committee.

Five workers were killed on the spot. Three bodies were recovered Monday and two others yesterday afternoon. Some 20 others were injured. One of them died yesterday morning in hospital.

The accident site has been cleared and investigations into the cause of the accident are underway.
