Four Qatari police officers were among those arrested, Egypt’s Al-Ahram newspaper reported.

Al Jazeera's offices in Cairo have been closed since July 3, when they were raided by security forces hours after toppled Egyptian President Mohamed Morsi was overthrown by the army.

Al-Ahram quoted security officials saying that they searched the office after receiving reports that firearms were inside. No arms were found during the search.

Security forces seized cameras and audio equipment, along with unlicensed transmitters.

Cairo's relations with Qatar deteriorated after the Egyptian army deposed Morsi on July 3.

The Persian Gulf emirate was a strong financial backer of Muslim Brotherhood rule and vehemently opposes the army's overthrow of Morsi and the ensuing bloody crackdown on his movement.
