The Islamic State group claimed responsibility on Tuesday for a bomb attack on a Cairo church that killed 25 people, the first claim for one of the worst attacks on the Coptic Christian community in recent memory.
ISIS identified the suicide bomber who carried out Sunday’s attack by the pseudonym Abu Abdallah al-Masri in a statement circulated on social media on Tuesday.
The bomber “got in between the crowd” and detonated his explosive belt, the jihadist group said in the statement.
The group said it would continue attacks against “every infidel and apostate in Egypt, and everywhere”.
President Abdel Fattah al-Sisi named the suicide bomber as Mahmoud Shafik Mohamed Mostafa, 22, during a funeral for the victims on Monday.
Egyptian authorities are battling an Islamist insurgency led by an Egyptian affiliate of ISIS.
