Protesters on Sunday closed the doors to Cairo's main administrative building as part of a growing campaign of civil disobedience around the country, employees and witnesses said. A group of protesters closed the doors of the Mugamma, a massive labyrinth of bureaucratic offices on the edge of Tahrir Square, leaving only a side exit for employees to leave, they said. Thousands are employed at the Mugamma, which houses passport offices, tax offices and various other government agencies.

Egyptian riot police deployed on Saturday near the presidential palace after a night of clashes between security forces and petrol-bomb throwing protesters that killed one man and injured nearly 100. The 23-year-old died of a gunshot wound as police used birdshot and tear gas on demonstrators who targeted the palace in rallies against Islamist President Mohamed Morsi late on Friday, a senior medical official said. Ninety-one people were also injured, said the official, while the interior ministry reported 15 of its men wounded by birdshot.

Egyptian security used water cannon and fired shots into the air as protesters threw petrol bombs and stones into the grounds of the presidential palace in Cairo on Friday, an AFP correspondent said. The clashes came amid rallies in several cities against Islamist President Mohamed Morsi following unrest that killed 56 people, mostly in Port Said, after 21 residents were sentenced to death over a football-related riot in 2012.
