Egypt prosecutor to question Islamists Egypt's state prosecutor has ordered an investigation into allegations that two leaders of the Muslim Brotherhood group instigated violence against protesters demonstrating against Mohamed Morsi, the Islamist president. Mr Morsi's supporters had clashed with secular, liberal and leftist protesters on Friday in Tahrir Square in central Cairo. The two sides pelted each other with stones and the Islamists dismantled a sound stage erected by their political opponents. More than 100 people were injured in the violence Mr Abdel Meguid Mahmoud's decision to question Mohammed el-Beltagy and Essam el-Erian follows accusations from female activists that the two Brotherhood leaders instigated the attacks. The protesters had come to the square to express their discontent with the president's performance since his election in the summer and to voice opposition to the Islamist-dominated constitutional assembly which is drafting Egypt's new charter. The Brotherhood has struggled to explain why it sent its supporters into central Cairo to the same location where it was known that anti-Morsi supporters would be protesting. The group's officials have said the attackers in the square were thugs pretending to be Islamists and that their people had not been told to congregate in Tahrir Square but in front of the High Court, which is also in central Cairo, to protest against the prosecutor-general himself. The president tried to remove Mr Mahmoud from his post on Thursday by appointing him as Egypt's ambassador to the Vatican. After an announcement to that effect was made, the prosecutor said he had not agreed to go and that he would stay in his post. Mr Morsi's move threatened to place him on a collision course with the judiciary because he does not have the authority to remove the prosecutor. On Saturday, after a meeting with the prosecutor and senior judges, the president backed down and all sides agreed there had been a misunderstanding. Mr Mahmoud was appointed to his post in 2006 under the previous regime of Hosni Mubarak, the former president ousted by a popular revolt last year. His removal has been a key demand of revolutionary activists angered by the weak cases presented by the prosecution service against Mubarak regime stalwarts and members of his security forces accused of killing protesters during the revolution. Mr Beltagy reacted to news that he would be interrogated by writing on his Facebook page that he was prepared to be questioned but urging the prosecutor to move equally fast on complaints filed against members of the former regime. The decision to interrogate the two leaders is likely to add to tensions in a political scene which is already deeply polarised between supporters of the Islamists and their opponents.
