State Security Prosecution ordered the detention of leading Muslim Brotherhood figures, Ahmed Abu Baraka and Mostafa El-Ghonemi, on Saturday, after charging them with “seeking foreign support” in Egypt’s ongoing political battle.

Arrested in an apartment in the Sayeda Zeinab district of central Cairo on Thursday, Abu Baraka is the latest in a string of arrests of the Brotherhood’s senior leadership, in addition to a wave of detentions of hundreds of members this week.

He is a member of the Brotherhood’s Guidance Bureau, whose lead figure, Supreme Guide Mohamed Badei, was arrested on Tuesday in Cairo.

El-Ghonemi, another member of the Guidance Bureau was arrested on Thursday in his apartment in Cairo’s Nasr City district.

Authorities have been leading a clampdown on Islamist figures since the ousting of former President Mohamed Morsi on 3 July. Clashes between Morsi’s supporters and security forces have been intermittent ever since.

Morsi was overthrown as part of the Armed Forces’ roadmap for Egypt, which was enforced following nationwide mass protests against the former elected president.

Brotherhood members and Morsi supporters have called on the international community to support them against what they describe as a “coup d’état”, and have been keen to speak to foreign media to get their voices heard globally.
