Three people have died after an overpass partially collapsed in South Korea, officials said.

Three others were injured when a vast part of the structure fell on to the street below in central Seoul.

The victims were crushed by debris and other wreckage after a section of a bridge deck suddenly collapsed, officials said.

Footage showed emergency services at the scene, along with a truck which was also damaged in the incident.

It occurred during a safety inspection after workers halted demolition work when noticing that a part of the structure had slightly sunk while concrete slabs were being cut, said Lee Jong-woon, an official at Seoul's Seodaemun District Fire Station.

The overpass, which was built in 1966, had been undergoing demolition since last August over safety concerns.

Traffic was diverted away from the site as twisted steel beams and shattered slabs of concrete hung precariously from the edge of the overpass.

Some debris also fell on a nearby railway, forcing the Korea Railroad Corp to suspend some services to Seoul Station.
