CAIRO, Aug 14 (Aswat Masriya) - The now-banned Muslim Brotherhood group said it "will not compromise Mursi's legitimacy", on the third anniversary of Rabaa al-Adaweya dispersal.

In a statement on Sunday, the group called on the international community to "prosecute the perpetrators of the massacre".  

The dispersal of Rabaa al-Adaweya sit in dates back to August 2013. The encampment was in support of elected Muslim Brotherhood president Mohamed Mursi who was militarily ousted in July 2013 after mass protests against his rule.

Rabaa’s dispersal saw the killing of at least 1,150 demonstrators, according to Human Rights Watch in a 2014 report which said that it “probably amounts to crime against humanity”.

The state's National Council for Human Rights, however, said in March 2014 that the death toll was 632, including eight security personnel. 

A few months after Rabaa's dispersal, Egypt listed the Brotherhood as a terrorist organisation as per a court ruling. The group's political wing, the Freedom and Justice party was dissolved in August 2014.

The majority of Muslim Brotherhood leaders and renowned figures including the Muslim Brotherhood’s Supreme Guide Mohamed Badie and the group’s second in command businessman Khairat al-Shater have been arrested since the ouster of Mursi.

The crackdown further involved forming a committee, back in September 2013, tasked with confiscating the funds and assets of the group.

The state insists the Brotherhood is behind the violent wave of militancy which has targeted security personnel since mid-2013.The Brotherhood continuously denies the accusations.
