Human rights groups are demanding the immediate release of Ashraf Hamdi, an Egyptian political cartoonist. Hamdi was arrested at his home in Giza on Sunday, shortly after he published a video marking the 10th anniversary of the revolution that toppled longtime dictator Hosni Mubarak. He faces charges of misusing social media sites and spreading false news. Amnesty International reports Egyptian officials are subjecting political prisoners to torture, cruel and inhumane detention, and are deliberately denying them healthcare to punish dissent, resulting in deaths and permanent injury.
