On 11 December 2016, a suicide bomber killed 29 people and injured 47 others at St. Peter and St. Paul's Church (commonly known as El-Botroseya Church), a chapel next to Saint Mark's Coptic Orthodox Cathedral, seat of the Coptic Orthodox Pope, in Cairo's Abbasia district. Egypt's President, Abdel Fattah el-Sisi, on Monday identified the bomber as 22-year-old Mahmoud Shafiq Mohammed Mustafa, who had worn a suicide vest. el-Sisi reported that three men and a woman have been arrested in connection with the attack; two others are being sought. ISIS claimed responsibility for the attack. This was the first time the church was ever bombed.
