The Egyptian army has condemned Sunday's "cowardly" bomb attack targeting churchgoers at the St Peter and St Paul church in Cairo's Abbassiya district, saying it will only increase the people's determination and solidarity in the face of terrorism and extremism.
An army statement also extended condolences to the families of the victims after at least 25 people were killed and 49 were injured in the attack.
The Coptic Church's spokesman Rev Paul Halim told Al-Ahram Arabic website that the explosion took place in the small church also known as El-Botroseya, which is attached to the Coptic Cathedral.
Following the attack, Egyptian president Abdel-Fattah El-Sisi announced that the country will observe three days of mourning.
Al-Azhar, the world's oldest seat of Sunni Islamic learning, also condemned the attack.
