The death toll could rise further as 19 of those injured were in critical condition.

More than 800 emergency workers and police officers from around the nation, including all available personnel in Seoul, were deployed to the streets to treat the injured.

The National Fire Agency separately said in a statement that officials were still trying to determine the exact number of emergency patients.

TV footage and photos showed ambulance vehicles lined up in streets amid a heavy police presence and emergency workers moving the injured in stretchers.

Emergency workers and pedestrians were also seen performing CPR on people in the streets.

An estimated 100,000 people had gathered in Itaewon for the country’s biggest outdoor Halloween festivities since the pandemic began.

The stampede is the biggest disaster since 304 people, mostly high school students, died in a ferry sinking in April 2014.
