South Korea is mourning the deaths of at least 151 people, mostly in their teens and 20s, who got trapped and crushed after a huge Halloween party crowd surged into a narrow alley in a nightlife district in Seoul.

Tens of thousands of people were believed to have gathered in Itaewon for festivities on Saturday night.
