Twenty-two million. That's the number of petition signatures anti-government protesters in the Egyptian capitol say they've gathered to oust President Mohamed Mursi. They're hoping millions, too, will march against him in Cairo Sunday, when he marks one year as Egypt's first freely-elected leader. (SOUNDBITE) (Arabic) FOUNDER OF TAMARUD MOVEMENT, MAHMOUD BADR, SAYING: "We invite the 22,134,465 Egyptians to be present tomorrow in Tahrir Square and in front of the Presidential Palace to see the fulfillment of the will of the Egyptian people in holding early presidential elections." The opposition accuses Mursi's Muslim Brotherhood of hijacking the revolution of 2011. But his supporters accuse them undermining democracy. Already, hundreds have been wounded and at least eight killed in street fighting between both sides, as political deadlock here deepens. On Saturday, the army was on alert and cities like Port Said quiet as activists prepared. (SOUNDBITE) (Arabic) EGYPTIAN TECHNICIAN, HAITHAM GADO, SAYING: "They want to prevent us from protesting on June 30. They want to prevent us from completing our revolution against the Muslim Brotherhood who have ruined Egypt." Protesters in Cairo chanted "tomorrow, tomorrow" - waiting for Sunday to come. But in another corner of the capitol, government supporters held their own PRO-Mursi sit-ins. They're beating their drums, but the risk of a violent showdown hangs in the air.
