A livestreamed comeback concert by K-pop megastars BTS drew 18.4m global viewers on Netflix, according to the streaming service.

Saturday's one-hour programme marked the first time all seven members - Jin, Suga, J-Hope, RM, Jimin, V, and Jung Kook - have performed together since October 2022, when they went on hiatus to complete their mandatory military service.

The free concert, staged at the historic Gwanghwamun Square, was attended by about 104,000 people, according to entertainment company Hybe - lower than the 260,000 anticipated by authorities.

Hybe's shares had risen in recent months ahead of the comeback tour and the release of their new album Arirang, but fell by 15.5% on Monday.

The event which marked the start of the band's sold-out, 82-date world tour, was livestreamed on Netflix to more than 190 countries, including South Korea.
