The United Nations human rights chief has called on Egypt to immediately release jailed British-Egyptian pro-democracy activist Alaa Abdel Fattah.
Volker Türk said his life was “at acute risk” after he escalated a hunger strike and stopped drinking water.
He began the strike in April to protest against the denial of consular visits.
His sister, Sanaa Seif, said: “All we know is that Alaa stopped drinking water 50 hours ago. We don’t know where he is. We don’t know if he is alive.”
“My mother waited outside the prison gates for 10 hours yesterday for her weekly letter. They didn’t give her one. She is back at those gates right now,” she told a news conference at the COP27 climate conference in the Egyptian Red Sea resort of Sharm El-Sheikh.
