A motorcyclist fell into a 20-meter-wide sinkhole that appeared in the middle of a road in Seoul on Monday, authorities said, with rescue efforts under way.
The sinkhole opened near an elementary school in Gangdong Ward, eastern Seoul, at 6:29 p.m., according to authorities.
Officials are currently conducting operations to rescue the motorcyclist.
A car driver who was passing down the road just before the collapse was also injured and sent to a hospital.
Seoul Mayor Oh Se-hoon called for safety measures to prevent further casualties, noting the sinkhole, affecting four of the six lanes on the road, is getting bigger.
