The Daesh group claimed responsibility for the recent deadly church blast in Cairo, that killed at least 25, the militant group said in a statement, circulated Tuesday, on social media websites.

The blast took place on Sunday morning, at Saint Peter and Saint Paul Church, known as al-Boutrosiya Church, which is adjacent to Saint Mark’s Cathedrtal, in Cairo’s Abassiya neighbourhood.

The Daesh statement said, a suicide bomber, referred to as, Abu Abdullah al-Masry, carried out the attack with an explosive belt, killing and injuring 80.

During an official funeral on Monday, President Abdel-Fattah al-Sisi revealed that, the attack was done by a 22-year-old suicide bomber named, Mahmoud Shafiq.

The attack came a day after an Egyptian top court confirmed a death sentence against Adel Habbara, a militant Islamist extremist, over a 2013 anti-military attack that killed at least 25 soldiers, in restive North Siani province.

Most of anti-government terror attacks that took place over the past three years were claimed by a Sinai-based group affiliated with the Daesh.

On Monday, a blast killed two military conscripts and injured three others in Sheikh Zuweid city of North Sinai, while on Friday, a bomb attack killed six policemen in Giza province, near the capital Cairo.

Terror attacks have been growing in Egypt since the military removed former Islamist president, Mohamed Morsi, in July 2013, in response to mass protests against his one-year rule and his now-outlawed Muslim Brotherhood group.

Later security crackdown on Morsi’s supporters left about 1,000 of them killed and thousands more arrested, while terrorist attacks killed several hundreds of police and military personnel.

A security campaign in Sinai killed over 1,200 militants and arrested a similar number of suspects, over the past couple of years, as part of the country’s anti-terror war, declared by former military chief and current President Sisi, following Morsi’s ouster.
