Protesters at COP28 climate summit demonstrate for imprisoned human rights activists from Egypt and the UAE. Demonstrators carry signs bearing the image of Ahmed Mansoor and Alaa Abdel-Fattah. The protest, organized by Amnesty International and Human Rights Watch, takes place within the U.N.-administered Blue Zone. However, just before the demonstration, protesters are ordered to fold over signs bearing the detainees' names. The U.N. cites security concerns. The Emirati government and COP28 organizers have not commented.
