Two South Koreans died and several others, including athletes participating in the World Aquatics Championships, were injured when an upper floor of a nightclub collapsed in the southern city of Gwangju early on Saturday, a fire department official said, APA reports quoting Reuters.
At least 10 people were injured when the structure collapsed on top of revellers around 2 a.m. KST (1700 GMT Friday), pinning people underneath, the Gwangju Fire Department official said.
