Protesters rally for ninth day in Egypt Thousands of angry protesters poured on to the streets of the capital and other Egyptian cities on Friday to protest against the government of President Mohamed Morsi in a ninth day of political unrest. Protesters emerging from Friday prayers at Maryam Mosque in the Mediterranean coast city of Port Said demanded justice for dozens killed in a week of violence ignited by a controversial court ruling sentencing 21 men to death for their role in a football riot last year. IN Middle Eastern Politics & Society "Leave, leave!" they chanted. With our souls, with our blood, we will sacrifice for you, Port Said! Protesters in Cairo, the capital, gathered near a northeastern mosque en route to the Itahadiya palace, the headquarters of the presidency. Others gathered in mosques across the city in preparation for marches to Tahrir Square. "Null and void," they chanted, describing the legitimacy of the Morsi government. Liars! The Brotherhood are criminals. They sold the revolution and they sold religion. There were also protests gathering in the second city of Alexandria and the industrial city of Suez. At least 50 people have died in political violence since the latest unrest began on January 24. Political leaders of both camps on Thursday signed a pledge brokered by elders at the Al-Azhar Mosque to stop the violence but it remains unclear how much sway they have over the country's restless youth, and many expect more bloodshed on Friday. Liberal, leftist and secular opposition groups on Thursday called for major protests against Mr Morsi's government, which is dominated by his Muslim Brotherhood and other Islamist groups. Critics accuse the Brotherhood of attempting to monopolise power in Egypt two years after young people led a revolution to overthrow the country's longtime authoritarian leader, Hosni Mubarak. They have demanded that the authorities forge a national unity government that includes more liberals, leftists and Coptic Christians, amend a constitution approved in a referendum with tepid turnout and replace a public prosecutor deemed an Islamist crony. The Brotherhood, whose allies and front groups have trounced their opponents in repeated elections, has accused the opposition of obstructing the country's social and economic progress by engaging in thuggery and serving the interests of the former regime. International observers and Egypt's armed forces have voiced alarm at the ongoing chaos and political paralysis, which has dimmed hopes for an economic recovery. Another Friday, another call by liberal and leftist opposition groups to head to the streets to protest against the government, this time to build momentum.
