Fifty-nine people have died in a crush among huge Halloween crowds in a popular nightlife area of South Korea’s capital, officials say.
Yonhap news agency cited emergency services saying 150 more had been injured in Seoul’s Itaewon district.
Videos from the scene show body bags on the streets, emergency workers performing CPR, and rescuers trying to pull people trapped beneath others.
It is not yet clear what caused the incident.
South Korea’s President Yoon Suk-yeol has called an emergency meeting.
There were reportedly 100,000 revellers in the area celebrating the first outdoor no-mask Halloween event since the pandemic.
Social media messages posted earlier in the evening show some people remarking that the Itaewon area was so crowded that it felt unsafe.
The BBC’s Hosu Lee, who visited the scene, said he saw “a lot of medial staff, a lot of ambulances, they were taking the bodies away one by one”.
Hosu Lee said there were thousands among the crowds, and a number of bodies covered in blue sheets, alongside a “ton of police”.
“A lot of young people have gathered here tonight. A lot of people came to the party and club, wearing costumes and a lot of people I’ve seen distraught and sad and there are chaotic scenes,” said Mr Lee.
