British trip-hop band Massive Attack has been prohibited from performing in Singapore after two members displayed a Palestinian flag during a Wednesday concert, breaching the city-state's strict regulations on foreign flag displays.

Singapore's police have barred British band Massive Attack from future performances following an investigation into a concert incident where band members displayed a Palestinian flag on stage. Two unnamed members held the flag during a Wednesday performance while one also shouted "Free Palestine," according to a police statement released Friday. Both individuals received stern warnings and entry bans to Singapore.

The city-state maintains strict legislation prohibiting the public display of foreign flags, national emblems, or banners without prior authorization. Singapore's media regulator is also examining whether licensing conditions were breached during the event. Police noted that the event organizer had previously acknowledged understanding these license requirements before the performance took place. Authorities stated they will reject any future applications for the band to perform in the territory.

Massive Attack, known for publicly criticizing Israeli military operations in Gaza, has become an advocate for Palestinian causes. Frontman Robert Del Naja was among over 200 people arrested during a London protest supporting Palestine Action in April. The band's latest incident highlights the tension between artistic expression and Singapore's strict public order regulations.

Singapore functions as a major concert venue for Southeast Asia, hosting extended engagements from international acts including Taylor Swift, Coldplay, Ed Sheeran, and Bruno Mars. Police appealed to both residents and international visitors to avoid bringing "foreign politics" into the country, stating such actions risk undermining social cohesion and respect for the legal system.
