Amnesty International has called for the immediate and unconditional release of an Egyptian photojournalist jailed for taking pictures of a protest where more than 700 people were killed.

Mahmoud Abu Zeid, known as “Shawkan” (pictured), could face the death penalty after being falsely accused of nine charges including murder, the charity has said.

Shawkan was arrested in Cairo on 14 August 2013 while taking photographs of a sit-in of thousands of people at the Rabaa al-Adaweya Square.
