South Korean boy band BTS is making a comeback with a full lineup, performing today at Gwanghwamun Square in Seoul. According to RTHK, authorities estimate that between 170,000 to 260,000 people will gather in the vicinity. The government has issued a level two disaster crisis alert, 'Caution,' for Seoul's Jung-gu and Jongno-gu districts. Traffic control measures are in place around Gwanghwamun, with bus routes being diverted and several subway stations closed, preventing trains from stopping.

Yonhap News Agency reports that authorities have deployed 15,000 personnel to ensure safety. To manage the large crowd and potential terror threats, the police have stationed approximately 6,700 officers, including over 6,000 riot police. A significant number of female officers are tasked with security checks, and seven foreign affairs patrol teams have been mobilized to ensure the safety of international fans and address language needs. The event organizers have also arranged for 4,800 staff members to assist.

In the morning, police installed metal detectors at multiple entrances to rigorously check for dangerous items. Additionally, they are controlling access to 31 nearby office buildings to prevent spectators from gathering on rooftops. Anti-drone vehicles and portable jamming devices are being used to prevent illegal drone flights.
