General Prosecutor decided on Thursday night that Muslim Brotherhood spokesman Gehad El-Haddad and five others will be detained for 15 days for interrogations held by State Security Prosecution, according to state-owned news agency MENA.

The detained include former Freedom and Justice Party (FJP) Qaliubiya MP, Ahmed Diab, Hesham Ismail, Mohamed Abu El-Fadl, Osama Abdel Moneim and Mohamed Ibrahim.

Prosecution charged El-Haddad and the other Brotherhood members of being members of  a “terrorist group,” publishing “false news” that “disrupt national peace”, “[threatening] national security” and “[portraying] a false image abroad.” They were also charged with inciting and participating in murder, sabotaging public installations and assaulting personal freedoms.

El-Haddad is the son of Essam El-Haddad, who served as advisor to former president Mohamed Morsi for foreign affairs. The elder El-Haddad was detained along with Morsi on 3 July and has remained in custody since.

Mohamed Abou Zeid, member of the Muslim Brotherhood’s Guidance Bureau, who was arrested with El-Haddad, was also detained for interrogations regarding charges of killings of protesters in front of the Supreme Guidance office in Moqattam during the protests of 30 June.
