The UK band reportedly expressed pro-Palestinian sentiments during a performance.

Singapore authorities are investigating Massive Attack after the British band reportedly expressed pro-Palestinian sentiments during a performance in the city-state. According to local media reports and eyewitness accounts on social media, two members of Massive Attack held up a Palestinian flag at the show on Wednesday, and reportedly shouted "Free Palestine", with some in the audience joining them. The BBC has contacted the organisers of the Singapore show and Massive Attack's management company for comment. Neither have responded yet. Singapore has strict rules on public speech and what it deems as demonstrations, arguing that it is necessary to regulate them to protect social harmony. Authorities have previously investigated public events related to the Israel-Gaza war. Earlier this year they fined several people for organising an unauthorised walk in support of the Palestinian cause. In response to BBC queries on Friday, a spokesperson for the police and the media authority said that "reports were lodged and investigations are ongoing". The spokesperson also said that the media authority is investigating a possible breach of licence conditions. Performances in Singapore, including concerts, usually require a permit. The BBC has asked Singapore authorities whether the band members or anyone involved in the production of the show have been detained or barred from leaving Singapore pending investigations. Authorities have yet to respond.
