SHENZHEN, CHINA - A total of 69 bodies have been dug up from the rubble of the massive Shenzhen landslide last month, with another eight people still unaccounted for, Xinhua news agency reported on Wednesday (Jan 13), citing the rescue headquarters.

Six people are still being treated at hospital, it added, while the authorities have identified 31 people suspected to be responsible for the disaster.

Police have arrested 16 of them and detained another nine, while six others are still at large.

The landslide occurred on Dec 20 when construction waste piled as high as 100m collapsed after rainfall and buried 33 buildings in an industrial area in the southern Chinese city.

It was the latest deadly accident to raise questions about China's industrial safety standards and lack of oversight over years of rapid economic growth.
