Egyptians protest against President Sisi

Tear gas has been fired to disperse demonstrators in Egypt, at some of the first protests since President Abdul Fattah al-Sisi took power in 2014. Hundreds of Egyptians filled Tahrir Square in Cairo demanding his resignation. The protests were in response to corruption allegations against President Sisi's government.
