Two police officers have been killed and several others injured following two bomb blasts near the presidential palace in the Egyptian capital of Cairo.
The attacks came on the first anniversary of the mass protests that led to the ouster of then-President Mohamed Morsi.
Egypt's state-run news agency reported that the blasts took place on Monday when police officers tried to dispose of explosives planted on the street.
A statement warning of the attack had been posted online prior to the blasts.
Egyptian authorities suspect the bombings were carried out by militants opposed to President Abdel Fattah al-Sisi.
Monday's bombing was the latest in a series of attacks on security personnel since last year's de fact coup.
Morsi supporters are calling for protests to be staged on Thursday, exactly one year after his removal.
