A fresh statement issued late Wednesday by a coalition supporting ousted Islamist president Mohamed Morsi, the National Alliance to Support Legitimacy (NASL), announced that it will participate in Islamist protests due to take place 28 November.
A lesser known group, the Salafist Front, has called for "a Muslim youth uprising" this Friday across Egypt in order to "impose Islamic identity without disguise."
The front announced it will demand the imposition of Sharia, or Islamic law, and the reinstatment of Morsi.
"Since November 2013, our vision is clear; we will continue our peaceful protest that gathers all Egyptians — Christians and Muslims — as one hand against the coup and against any kind of aggression on our identity," read the NASL statement.
The NASL also warned that they will continue a week of protests in case toppled autocrat Hosni Mubarak and his interior minister, Habib Al-Adly, are acquitted.
A criminal court is expected to give its final verdict 29 November on Mubarak's retrial on charges of unlawfully killing protesters during the 25 January Revolution.
Since the Salafist Front's call for protests, many arrests have taken place against members of the front. The Muslim Brotherhood, designated a terrorist group in December, announced their support for Friday's protests.
In contrast, Egyptian Salafist groups like Al-Nour Party and Al-Daawa Al-Salafiyya movement rejected calls for protests on Friday.
Al-Nour started a campaign under the slogan "Egypt without violence" in response to the protest calls. Younes Makhioun, president of the party, said in a public conference Monday that calls for violence are Egypt's most dangerous challenges.
Meanwhile, rapid deployment divisions of Egyptian security forces will be intensifying their presence all over Egypt in response to calls for protests, according to official statements by the interior ministry and the military.
