The raid reportedly occurred shortly after the network aired a statement by now-ex-president Mohammed Morsi, who declared that “we by ourselves can bypass the obstacles” and “the will of the people… cannot be canceled.”

Reuters quotes an Al Jazeera employee in Cairo as saying that his colleagues were arrested in the studio and they were “prevented from broadcasting” a pro-Morsi rally.

There is also a video making the rounds on Twitter that reportedly marks the exact moment when the studios of Al Jazeera Mubasher Misr were raided by security forces.

The Qatari-owned Egyptian arm for Al Jazeera first began broadcasting following the 2011 toppling of former president Hosni Mubarak. It has since then been accused by Egypt’s opposition of being sympathetic to Morsi and the Muslim Brotherhood.

Egypt's military-led authorities shut down several other stations, including Al-Hafiz and Al-Nas, after Morsi was toppled by the army.

Muslim Brotherhood-owned Egypt25 was also forced off air and its managers arrested shortly after General Abdel Fattah al-Sisi, head of Egypt's armed forces, announced a plan for a new political transition, the state news agency MENA reported.
