More than 100,000 fans turned out to see K-pop superstars BTS's first concert in nearly four years, their label said Sunday, a smaller number than originally expected for the highly anticipated event in central Seoul.

BTS will stage its long-awaited comeback concert on Saturday night at Seoul’s Gwanghwamun Square. The square is one of South Korea’s most famous landmarks, representing its royal heritage as well as its political and cultural life.

Over 250,000 fans, including 22,000 lucky "Golden Ticket" winners, attend group's first concert in four years

Organizers expected to draw a crowd approaching a quarter-million people, making it one of the largest public music events ever held in South Korea.

After a four-year break, K-pop supergroup BTS returned Saturday with a massive, free comeback concert in Seoul, where thousands of police locked down a central boulevard for the Netflix-exclusive spectacle that drew tens of thousands of fans.
