ISIS has claimed responsibility for a suicide bombing at a church in Cairo that killed 24 Christians.

The terrorist group named the bomber as Abu Abdullah al-Masri, thought to be a nom de guerre. Egyptian President Abdel Fattah el-Sisi said the attack, whose victims were mainly women and children, was carried out by 22-year-old Mahmoud Shafiq Mohammed Mustafa.

The bomb detonated outside a chapel adjacent to St Mark’s Cathedral, seat of the Coptic Orthodox Church, while the faithful attended a Sunday Divine Liturgy.
