Osama Amir, 22, a student walking from the fight, said he did not know how it started or why. “People have lost confidence in the central security forces, so when there is a chance to beat them up, we will beat them up,” he said.
A little while later, another street fight broke out when demonstrators passed the office of the Muslim Brotherhood Web site on their way to the square and threw rocks at it. Other civilians — it was unclear whether they were annoyed neighbors or Brotherhood supporters — rushed out to strike back at the protesters, and a street vendor’s kiosk was burned in the melee.
Simultaneously, a group of masked men broke into the building and ransacked the Brotherhood office, overturning furniture, destroying computers and breaking glass. Neighbors of the building said the attack appeared to have been planned because the men had brought acid to break through a padlock.
The Brotherhood, hoping to avoid the kind of factional clashes that killed 10 people in December, urged its supporters to stay away from the square and observe the anniversary with community service projects around the country.
Both the Brotherhood and its opponents are now looking ahead to parliamentary elections expected to be held in April, and critics of the Brotherhood contended that its community service drive was in part an effort to curry favor with needy voters. The opposition had poured most of its energy into Friday’s demonstrations, and its critics said it was once again wasting its time on street protests while the Islamists had already turned their attention to the more important electoral battle.
“It is important that people go down to the square, if for no other reason than to remind Egypt, and themselves, that something really special happened during those 18 days two years ago,” said H. A. Hellyer, a researcher based here with the Brookings Institution. “That energy, however, can’t stay in the square,” he said. “It’s got to be channeled.”
But some demonstrators argued that the public protests were a first step toward building a more potent political movement that might someday counterbalance the Islamists. “Nothing tangible will come of today, and I don’t think anything tangible with happen with the elections,” said Ayman Roshdy, 57, a retired marketing consultant. “But there is hope. What is happening today is part of the process of building hope.
“The Islamists have been saying that they are the good guys,” he continued. “Now they are in control and they are being exposed by the minute. And we are building a political movement that will help us to produce a reasonable government.”
By late afternoon, other marches from around the city, some led by well-known leaders of the political opposition, were streaming toward the square and the crowd was expected to swell toward nightfall, along with the potential for more violence.
