Supporters of Egypt's deposed president Mohamed Morsi run for cover from tear gas fired by riot police during clashes in the northeastern part of Cairo's Nasr City district on January 3, 2014. Demonstrators threw stones and set fire to tyres in the street after an Islamist alliance backing Morsi called for demonstrations ahead of a new hearing in the former president's trial on January 8.
