No fewer than four people had been killed after a bridge under construction collapsed in South Korea on Tuesday, news agency Yonhap reported.
Six people were injured in the accident, some 80 kilometres south of Seoul, five of them seriously.
Yonhap said five 50-metre-long steel beams holding up the bridge collapsed one by one as workers used a crane to move beams between piers.
Those killed or injured were working beneath the bridge.
The workers were constructing a section of the Seoul-Sejong road expressway. (dpa/NAN)
