The vast majority of Egypt's political forces are preparing to rally in Cairo's Tahrir Square on Friday as frustration is mounting at the slow pace of reforms in the country.
Five months after the fall of the Hosni Mubarak regime, most political parties are dissatisfied with how the ruling Council of the Armed Forces (SCAF) and the transitional government are carrying out reforms.
"The revolution continues, as implementation of many demands has stalled over slow justice, rampant crime and reluctance to put decisions into practice," the organizers said in their statement.
The acquittal of three former ministers accused of corruption and police officers charged with firing at protestors during the 18-day uprising against Mubarak caused outrage among relatives of the victims.
Last week, thousands gathered at Tahrir Square, where the revolt started on January 25. Police used tear gas to disperse the protesters, leaving nearly 600 injured.
The health and interior ministries are also preparing for the event, fearing that protests may again turn violent. Some 80 ambulance vehicles and three mobile operating suites will be stationed near Tahrir Square.
Police will be deployed in nearby districts and will interfere "only in an utmost emergency situation," Interior Minister Mansour el-Essawy said.
