A motorway bridge collapse has killed at least three people and injured seven as spans of the partly built structure collapsed one after the other.
The accident took place on Tuesday in Anseong, about 70km (43.5 miles) from Seoul, when five 50-metre steel support structures collapsed in turn after being hoisted into place by a crane, the Yonhap news agency reported.
The national fire agency said three people died and six were injured, including five who were in a critical condition.
Sections of partly constructed elevated motorway in Anseong fell one after the other, killing at least three construction workers.
Hunting for survivors, rescue workers at the site were seen examining twisted metal struts and fractured concrete slabs below the columns of the highway bridge.
