Ahead of COP27, Egyptian authorities arrested hundreds of activists in a broad crackdown on dissent. They also published guidelines limiting protests during COP27 to designated zones and will require 36 hours advance notice. On Sunday, Sanaa Seif arrived in Sharm el-Sheikh to demand Egyptian authorities release her brother Alaa Abd El-Fattah, the Egyptian-British political prisoner. Abd El-Fattah intensified his six-month hunger strike by giving up water altogether as the climate conference opened. British Prime Minister Rishi Sunak has expressed support for Alaa Abd El-Fattah and vowed to raise the issue while he is at COP27. In a letter, Sunak said securing his release was “a priority for the British government both as a human rights defender and as a British national.”
