A suspicious object created panic Sunday morning after it was found next to the Virgin Church in Al-Saff, Giza, as Christians celebrated Palm Sunday.
State-owned Al-Ahram newspaper reported that a bomb was defused on the scene, but added later that it was only bricks wrapped in duct tape and wires.
Security cordoned off the area as a bomb squad searched for more explosives, Al-Ahram added.
Christians flocked to various churches across the country to celebrate Palm Sunday, a feast that falls on the Sunday before Easter.
Churches, monasteries and Christian-owned properties were targeted following the violent dispersal of two pro-Brotherhood sit-ins last August.
Last January, an armed assault targeted a church in the 6th of October City in Giza, killing one policeman.
The attack was preceded by another on the Virgin Mary Church in Giza’s Warraq district in October, when two armed gunmen on the back of a motorbike opened fire on a gathering of people who were attending a wedding, leaving four people dead.
