Dozens of women held a vigil Sunday outside Egypt's presidential palace, challenging a law that restricts protests and calling for the release of thousands of prisoners detained for violating the controversial measure. Organizers said they didn't seek prior permission from authorities to stage the vigil near the palace of President Abdel-Fattah el-Sissi. Police formed a cordon around the women, who raised photos of detainees. Some protesters raised banners that read: "Ramadan is not the same without you," in reference to the Muslim holy month of fasting that brings families together.
