At least 154 dead, 82 injured in stampede during Halloween festivities in Seoul

A mass of mostly young people celebrating Halloween in Seoul became trapped and crushed as the crowd surged into a narrow alley, killing at least 154 people and injuring 82 others in South Korea's worst disaster in years.

Emergency workers and pedestrians desperately performed CPR on people lying in the streets after the crush in the capital's leisure district of Itaewon on Saturday night.

Those killed or hurt were mostly teens and people in their 20s, according to Choi Seong-beom, chief of Seoul's Yongsan fire department. The dead included 19 foreigners, he said, whose nationalities weren't immediately released. The death toll could rise further as 19 of those injured were in critical condition.
