Ahly's Ultras Ahlawy gathered outside the Ahly Sporting Club in Zamalek from midday, where they were joined by Zamalek's Ultras White Knights – who arrived from Sphinx Square in Muhandiseen – and others from Tahrir Square. Together they marched to the interior ministry after altering their original plan to march on Parliament.
Many protesters wore black and wept with grief. "I have three children who are Ultras Ahly, and if any of them had died, I don’t know who I would have turned to," Mohamed Omran told Ahram Online in tears.
