Demonstrators chant slogans in support of Egypt's President Mohamed Morsi and the Islamic Shariah around Al-Nahda Square in front of Cairo University, Friday. — Reuters CAIRO — Thousands of Islamists protested in Cairo Friday against violence that has marred anti-government demonstrations, showing support for President Mohamed Morsi, the Muslim Brotherhood politician elected head of state last year. The “Together against Violence” rally — also called “Checkmate Friday” — was called by a Salafi Islamist group that waged an armed revolt against the state in the 1990s. Al-Gama'a Al-Islamiya, whose leadership renounced violence more than a decade ago, has entered mainstream politics since autocratic president Hosni Mubarak was overthrown in 2011. The Muslim Brotherhood and its Freedom and Justice Party said it backed Friday's rally in a symbolic way but did not mobilize supporters for the event, meaning the numbers were smaller than at previous Islamist protests. Around 60 people have been killed in Egypt since late January in unrest touched off by the anniversary of the uprising against Mubarak and exacerbated by a court ruling that sentenced 21 people to death over a soccer stadium disaster a year ago. It has been the worst bloodshed since Morsi assumed office, underlining the instability that continues to thwart government efforts to restore a sense of normalcy and revive an economy in crisis by attracting fresh investment and tourism. The unrest has been stirred by anger at Morsi and his Islamist backers, who the opposition says have betrayed the revolution and sought to monopolize power — accusations dismissed by the Muslim Brotherhood. Repeating the pattern of recent weeks, Morsi's opponents rallied again Friday, this time gathering outside El-Quba, one of the presidential palaces in Cairo. Recent protests have routinely turned violent, with government buildings, police stations and the presidential palace coming under attack. But, “the person who came (to power) through ballot boxes will not leave by petrol bombs,” said a cleric who led the crowd in Friday prayers as the rally got under way outside Cairo University. “He who came to power by direct, free choice will not leave by the rocks thrown by children,” he said The crowd grew to several thousand after prayer. “No to Violence. Yes to Shariah (Islamic law),” declared a banner held aloft from the crowd. “With our blood and souls we will sacrifice ourselves for Islam!” chanted the crowd. “The people want an iron fist,” read another banner. Some people journeyed in from the provinces for the rally. At one point, the mother of Khaled Al-Islambouli, one of the Islamists behind president Anwar Sadat's 1981 assassination, appeared on stage, drawing cheers as she waved to the crowd. “Mohamad Morsi is a legitimate leader who was elected by the will of the people,” said Mohamad Omar, from Mansoura, north of the capital. He came on a bus chartered by Al-Gama'a Al-Islamiya. “The opposition's methods of violence, petrol bomb-throwing, igniting fires and causing destruction is not accepted,” added Alaa Abdulwahab, a 45-year old who had traveled from Minya, a four-hour journey south of Cairo. — Reuters
