At least 151 people were killed and 76 others were injured in a crowd surge on Saturday night in South Korea's capital, Seoul, after Halloween celebrations turned deadly.
It was estimated that 100,000 people flocked to the neighbourhood to celebrate Halloween, forming the largest crowds seen in the area.
Choi Seong-Beom, chief of Seoul's Yongsan fire department, said the death toll could rise, and the exact number of people in critical condition is unknown.
Emergency workers from around the country were deployed to the district to treat the injured in a temporary medical center.
