Egypt: Four police killed in drive-by shooting in Cairo

Four Egyptian security personnel have been killed in a drive-by shooting, security officials say.

The shooting happened in the Saqqara area, some 35km (22 miles) south of the capital Cairo.

The unidentified attackers were riding a motorbike when they opened fire on a police checkpoint, Reuters reports.

Egypt has seen regular attacks on security forces since the army ousted Islamist President Mohammed Morsi in July 2013.
