Victims in their late teens and 20s accounted for the age group most affected by the accident, the authorities also said. It is not yet known whether the victims included minors. Video footage showed rescue workers and ordinary people conducting CPR on victims on the streets.

Fire authorities initially received dozens of reports from people in the Itaewon area about patients with breathing difficulties. The first report was made around 10:15 p.m. Rescuers sent to the scene had administered CPR on dozens of victims on a nearby road. Seoul Horror: 59 Dead, 150 Injured After Stampede at Halloween Party in Itaewon (Video).

"As people in the front fell over, those in the back were crushed," a witness in his 20s told Yonhap news agency. Rumours at the scene were that a crowd of people had flocked to a place to see a celebrity or candies laced with drugs had been distributed at clubs, but the exact cause of the accident is yet to be known.

South Korean President Yoon Suk-yeol addressed the nation live from the presidential office, saying Saturday's "tragedy and disaster should never have happened".

The President also announced a period of national mourning over the stampede. Before addressing the nation, Yoon also presided over two successive emergency meetings, ordering officials to swiftly administer first aid and treat the injured, the presidential office said.

The President also ordered officials to deploy emergency medical officials to Itaewon and secure emergency beds. After presiding over an emergency meeting on the stampede, Yoon instructed officials to thoroughly investigate the cause of the accident.

Separately, Prime Minister Han Duck-soo instructed officials to make utmost efforts to minimise damages. Seoul Mayor Oh Se-hoon, who is on a visit to Europe, decided to return home in the wake of the accident, city officials said.

As of early Sunday, some 270 missing reports were made in connection with the accident, the Seoul city government said. Police said they are making utmost efforts in confirming the identity of the victims and then making contacts with their family members.

Police plan to launch an investigation soon into whether bars and clubs in the area were in compliance with safety regulations. US President Joe Biden expressed his "deepest condolences".
