The death toll in Cairo's St. Peter and St. Paul Church December's bombing climbed to 29 on Saturday as Demyana Amir, a 14-year-old girl, died from her wounds, Coptic Orthodox Church official Bassem Salah told Ahram Online.

Salah said that Amir was admitted to the hospital following the attack with liver laceration but her condition continued to deteriorate.

On 11 December, a suicide bomber, identified as 22-year-old Mahmoud Shafiq Mohamed Mostafa, set off explosives in the women’s section of the St. Peter and St. Paul Church in Cairo instantly killing 23 people, mostly women and children, and wounding over 40 others.

Five more of those injured succumbed to their wounds in the weeks since. 

The Islamic State militant group has claimed responsibility for the attack, whereas the Egyptian Ministry of Interior accused members of the banned Muslim Brotherhood organisation residing in Qatar of plotting the bombing.
