Update: Protesters, police square off near Qubba

Protesters clashed with security forces across the country on Friday.

The Muslim Brotherhood called for a million man protest under the name of "Vengeance is Coming.” Today marks 100 days since 36 detained Brotherhood supporters died in a police vehicle headed towards Abu Zaabal Prison.

Early Friday evening, security forces clashed with Brotherhood supporters at the Qubba Bridge metro station in the greater Cairo area after the protesters reportedly shot off fireworks inside the station, reported the state-run news site Egynews.

At the Qubba Palace, security forces fired tear gas to disperse Brotherhood supporters, demanding they end the protest as they did not have the security clearance as required by the new protest law.

In Cairo's Giza district, security reinforcements arrived on Haram Street to disperse Brotherhood supporters after clashes there intensified. The state-run Middle East News Agency (MENA) reported that three troops of reinforcements and six armored trucks were sent to the area to suppress the violence.

The march had turned violent earlier in the day, when security forces fired tear gas to disperse the protesters as they blocked the road, MENA reported.

A security source in Giza claimed that protesters threw Molotov cocktails and fired shots at the police, who responded only with tear gas and did not resort to excessive force, said Egynews. 

Protesters chanted against the Armed Forces and the police, while holding up signs bearing the black and yellow icon in memory of the violent dispersal of the sit-in at Rabea al-Adaweya in August that left hundreds dead.

In Suez, security forces broke up protests and chased demonstrators into side streets. Soon after, military personnel deployed armored vehicles to prevent protesters from reaching the main Arbaen Square.

The same scenario was repeated in Damietta and Fayoum, where security forces dispersed protests using tear gas and pursued demonstrators on foot.

Protesters took to the streets today to demonstrate against multiple actions taken by security forces in recent weeks, including the passing of a strict law regulating protests. Furthermore, on Wednesday, 11-year prison sentences were handed down to 21 women and girls convicted of offenses while protesting in support of ousted President Mohamed Morsi.

Several other activists, including Alaa Abd El Fattah, have also been arrested on charges relating to inciting or participating in protests.
