More than 100 protesters gathered on Sunday on the sidelines of the COP28 U.N. climate summit to call for a ceasefire in the Israel-Hamas war, an unusual sight in the United Arab Emirates where freedom of expression is limited. The UAE tolerates little dissent and bans organised groups like political parties and labour unions, but as hosts of the annual U.N. conference, the Gulf state is allowing protests to take place at COP28 itself. Holding banners calling for a "ceasefire" and "climate decolonisation", activists in the Dubai Expo City chanted "Free, Free Palestine".
