More than 150 people were killed in a stampede at a Halloween event in central Seoul, officials said Sunday, with South Korea's president vowing a full investigation into one of the country's worst-ever disasters.
The crowd surge and crush hit in the capital's popular Itaewon district, where estimates suggest as many as 100,000 people -- mostly in their teens and 20s -- went to celebrate Halloween on Saturday night, clogging the area's narrow alleyways and winding streets.
