Egypt Protesters Storm Cairo's Oct. 6 Bridge

While Thursday's protests remained peaceful, the cause of the rally was nearly the same. Hundreds of people gathered on the bridge over the Nile, one of the city's busiest roads, to demand an end to military rule.

The Supreme Council of the Armed Forces took control of Egypt when the January-February 2011 protests forced Mubarak to resign, and many Egyptians now fear that the council has no intention to honor its promise to establish civilian rule.

It has been four months since the revolutionaries did anything … but the crises have increased, Hesham el-Shal, a coordinator for the Second Revolution of Rage protest group, told the Associated Press.

Those who held the Oct. 6 bridge on Thursday will be joined by what could be thousands of others in Tahrir Square on Friday. More than 30 political groups and parties representing the entire spectrum of Egyptian society have signed on to rallies in Cairo to defend the gains of the revolution and to loudly proclaim their dissatisfaction about the reappearance of a number of former Mubarak top officials, according to Egypt's Al Arabia.

On Friday, popular Islamist parties like the Muslim Brotherhood and the Salafist Front will join with secular activists and political groups like the Coalition of Revolutionary Forces and the National Front for Justice and Democracy to say with one voice that they want constitutional rule.

Additionally, a group of activists from Suez began marching on Cairo by foot Wednesday to join the protests in Tahrir.

We are showing the military council that if someone would walk this distance for a cause, he could do anything else for the same cause, Mohamed Ghareeb, a 20-year old student participating in the march, told Reuters.
