SEOUL, Sept. 11 (Yonhap) -- K-pop sensation BTS will broadcast two of its upcoming South American tour dates live to movie theaters in more than 80 countries, according to an announcement by its agency, BigHit Music. The screenings will feature the third day of the group's Buenos Aires stop on Oct. 24 and the second day of its Sao Paulo concerts on Oct. 30, local time. Approximately 3,800 theaters globally are expected to participate in the event. Due to time zone differences, audiences in Asia, Australia, and other regions will view delayed broadcasts, which may occur one to two days after the original performances. The "Arirang" world tour's Latin American leg is set to commence on Oct. 2 in Bogota, with subsequent stops planned in Lima, Santiago, Buenos Aires, and Sao Paulo.
