Egyptian women rights advocate Dalia Aziada posted this tweet after several Coptic churches were burnt across Egypt following a brutal military operation on August 14 2013, to clear Muslim Brotherhood supporters from sit-in camps in the capital Cairo, where they have been demanding ousted president Morsi's reinstatement for weeks.

The clearing operation resulted in at least 638 deaths according to the Egyptian government. A Muslim Brotherhood spokesman has said 2,000 people were killed in the “massacre.”

Dozens more were killed on August 16, as Muslim Brotherhood supporters clashed with security forces in the “Day of Anger.”
