Egyptians gathered in their thousands in Tahrir Square in Cairo for a second night running on Saturday. These protesters are getting ready to mark Sunday's anniversary of the president's first full year in office with fresh calls for his resignation. Mohamed Mursi's opponents say they've got 22 million signatures on a petition urging him to step down. But supporters of the Islamist president are also ready to defend the country's first freely-elected leader. They're planning their own rallies. Fears of violence are running high. Security forces say they're preparing to deal with trouble.
