Human Rights Watch documents the destruction and looting of Christian churches, businesses, schools, and even an orphanage by Muslim Brotherhood activists and other Islamists all over Egypt. All of this in retaliation after police and security forces tried to break up the Muslim Brotherhood sit-ins in Cairo.
Two employees on a tourist boat restaurant who were hiding when it was attacked, were found dead. One was a Christian, the other was a Muslim.
No-one came to help before or after the attacks.
