Egypt's leftist National Progressive Unionist Party, commonly known as Al-Tagammu, has accused the Muslim Brotherhood of attempting to assassinate its spokesman and leading member Nabil Zaki.
In an official statement Saturday, Al-Tagammu said that Zaki, a prominent writer in his seventies, was hospitalised after being attacked on Friday afternoon, his car "completely destroyed."
Zaki was reportedly attending the Independence Movement Conference in the Muslim Youth Club in Downtown Cairo.
He has been allowed to leave hospital early Saturday after receiving treatment. He suffered a wound to the head and several bruises to the face.
Thousands of Islamist protesters held a rally at the High Court in Downtown Cairo to demand a "purge of Egypt's judiciary" Friday when clashes erupted between them and unknown opponents leaving at least 87 injured.
In addition, the party said its member Mohamed Nasr was "run over by a car in Tahrir," accusing Brotherhood members of being behind the assault.
According to the statement, Nasr is in critical condition and also hospitalised.
Al-Tagammu called on the Brotherhood to officially apologise for the incident and also demanded that the Ministry of Interior investigate and hold the perpetrators accountable.
The party, a critic of the Muslim Brotherhood, said it has the "ability to respond against these fascist aggressors" and that "even though [Al-Tagammu] currently respects the law which the Brotherhood violates ... it warns that its patience may run out if such incidents reoccur."
