HAIKOU - A concrete wall collapsed at a local farm in the southernmost province of Hainan Saturday at about 4:00 am, claiming six lives so far.
The mishap occurred when the wall of a cistern collapsed and destroyed a makeshift work shed nearby. Four of the dead were workers from Guizhou province, and the two others were local guards.
An investigator said the accident was most likely caused by rains that led to geological changes that cracked the wall.
One man has been detained for interrogation by local police.
