Egypt Minister: 'No country immune from attacks'
In Egypt security has been stepped up at tourist sites for the Eid al-Fitr holiday marking the end of the fasting holy month of Ramadan.
Militants have hit hard in the capital, Cairo, recently assassinating the chief prosecutor and detonating a car bomb near the Italian consulate.
Egypt's Foreign Minister Sameh Shoukry says the country faces a growing threat from extremist groups including the self-styled Islamic State.
He told the BBC's Orla Guerin that the latest bombings in Cairo were more organised than those in the past.
