An Egyptian police officer was shot dead on Thursday (September 19), state media reported, during a security operation on the outskirts of Cairo aimed at reasserting control over an area where gunmen killed 11 policemen last month.

The police had earlier fired tear gas and exchanged gunfire with gunmen in the area of Kerdasah, state TV reported.

Kerdasah police station was abandoned after it was hit with rocket propelled grenades and gunfire on Aug. 14 - the same day security forces moved against protests by supporters of deposed President Mohamed Mursi in Cairo, killing hundreds.

Kerdasah, known for producing and selling fancy fabrics is 14 km from Cairo and known to be an Islamist stronghold.

Mursi's exit was triggered by mass protests that led counterprotests nationwide. Violence between his supporters and security forces included massive attacks on police stations, security officers and churches.

At least 1,000 people have died in the violence with most deaths coming during the security forces' dispersal of two pro-Mursi sit-ins in Cairo on Aug. 14. About 100 police officers also died in the clashes.

Nearly 2,000 Islamist activists and politicians have been arrested since Mursi's ouster.
