A huge fire engulfed an underground parking garage of an apartment building under construction in central South Korea on Tuesday, leaving at least three dead and 37 others injured, Yonhap reported.

The blaze started at 1:10 p.m. local time at the Treeshade apartment construction site in the central administrative city of Sejong, sending flames and black smoke rising into the sky. 

Construction firm officials estimated the number of workers at the site at the time at 169.

About 49 firetrucks and 200 firefighters battled the blaze. But firefighters had difficulty battling the flames since there was no fire extinguishing system in the building under construction.

One Chinese national was among the dead, and one were severely wounded, while 13 other Chinese suffered minor injuries.

All the injured Chinese were hospitalized, and seven of them were released from hospitals after medical treatment, while the other seven are still hospitalized with non-life-threatening injuries.
