CAIRO (AFP) - Hundreds of supporters of Islamist President Mohamed Mursi took to the street on Friday to denounce violence after weeks of bloody protests between police and anti-Mursi protesters. The Islamist Construction and Development Party had called for the rally under the slogan "Together against violence", blaming the liberal-led opposition for unrest that has recently swept the country. "It's all the opposition's fault. They are behind the violence," protester Mohamed Ahmed said. Protesters also called for the release of blind Sheikh Omar Abdel Rahman, holding up pictures of the Egyptian cleric jailed in the Unites States for his role in the 1993 World Trade Center attack. "Islam is coming", "Holy Quran is our constitution," demonstrators chanted as they marched towards the main rally near Cairo University. "Mursi! Mursi!" others cheered as they waved Egyptian flags and held up banners that read "No to Violence, Yes to Sharia" or Islamic law. The Muslim Brotherhood, on whose ticket Mursi ran for the presidency, said it would symbolically join Friday's rally, without mobilising its supporters on the street. Egypt has been deeply divided between Mursi's mainly Islamist supporters and a wide ranging liberal-led opposition calling for rights and demanding the separation of state and religion. In recent months, Egypt has witnessed regular, often bloody, protests against Mursi. His opponents say he has betrayed the revolution that toppled Hosni Mubarak, accusing him of using his power to promote the interests of his Muslim Brotherhood, long banned under his predecessor. They also accuse him of failing to reform the interior ministry whose police has been accused of abuse and corruption.
