Two Egyptian women protesters pay their respects in front of a spot designated for pictures of protesters killed during the Egyptian revolution and verses of Quran that reads "do not kill the soul that God restricted you from killing without justice," at Tahrir Square, Cairo, Egypt, Friday, Dec. 7, 2012. Thousands of Egyptians took to the streets after Friday midday prayers in rival rallies and marches across Cairo, as the standoff deepened over what opponents call the Islamist president's power grab, raising the specter of more violence.
