The UK band says they are "surprised and disappointed" by their treatment over shouting "free Palestine" at a concert there.

Massive Attack have said they were "surprised and disappointed" by their treatment by Singaporean authorities after expressing pro-Palestine sentiments during a performance in the city-state. The group wrote on Instagram on Sunday that its members were "detained by the police, isolated and separately questioned", with some subject to hotel room searches and temporary passport confiscation. The band's two members held up a Palestinian flag during its 29 July show there and shouted "free Palestine" alongside members of the audience. Singapore, which has stringent rules on public speech and assembly, subsequently said it had indefinitely banned Massive Attack from returning to the country. A police spokeswoman told the BBC on Friday that the two band members would not be allowed to re-enter Singapore and were barred from performing there. Robert Del Naja and Grant Marshall were "given stern warnings" concerning alleged offences under two laws that restrict the public display of foreign flags and regulate political expressions at public events. Massive Attack said that before the show and again at the end "large sections of the auditorium organically led chants of 'Free Palestine', presumably aware but undeterred that this spontaneous expression alone could violate their government's censorship laws". The band did not address the ban directly, but described the situation as a "surreal experience" and said they "did not imagine that merely holding up the flag of a sovereign state recognised by 157 countries would violate any law".
