CAIRO, Egypt (CBS) -- Violence between riot police and protesters began early on Tuesday (November 27), a day expected to be one of opposition action in the Egyptian capital.
Opponents of President Mohamed Mursi pressed ahead with a protest to demand the scrapping of a decree extending his powers, rejecting the Islamist's attempt to defuse a crisis that has brought violence back to Cairo's streets.
Mursi was accused of giving himself the powers of a modern-day pharaoh when he issued the decree last week that prevents legal challenges to any decision he takes until a new parliament is elected.
Protesters have camped out in Tahrir Square since news of Mursi's decree was made public, repeatedly clashing with riot police holed up in a disused school and deployed on rooftops firing tear gas into crowds.
Tuesday saw more clashes gathering momentum on side streets near Tahrir Square as police fired tear gas at protesters, and stones were thrown in response.
