While military police have been involved in a number of rounds of clashes with protesters, Friday’s was one of the first crackdowns executed directly by the Egyptian Armed Forces.
“We are unsure exactly why the Army has used such excessive force against the protesters,” said human rights lawyer Ahmed Seif al-Islam, father of jailed blogger Alaa Abdel Fattah. Seif al-Islam’s two daughters, Mona and Sanaa, suffered beatings Friday at the hands of the military, he said, though by the evening they were safe at home.
“It may be that the Army is raising the heat on protesters voicing their opposition to the military regime, while working hard to turn the population against the protest movement,” said Seif al-Islam. “Otherwise, there really is no explanation for the extreme brutality witnessed Friday.”
