After more than 150 people died in a deadly crush in Seoul on Saturday night, the BBC looks at how the tragedy unfolded.
By early evening on Saturday, thousands of mainly young revellers had converged in Itaewon in the centre of the South Korean capital, a lively party spot whose warren-like streets and alleys are filled with bars and restaurants.
Some accounts say 100,000 people had descended on the area to celebrate Halloween, excited about the prospect of partying again after two years of strict Covid restrictions in the country.
Nuhyil Ahammed, 32, was among the crowd. The IT worker from India lives nearby and had been to Halloween parties in Itaewon for five years running.
Last year the celebrations had been lively, but under control, with police preventing people from entering busy areas. Things were very different this year, he said.
