The victims included a number of children.
More than 600 parishioners were inside the church for a service on Sunday when the bombers struck.

"This was a security lapse," (THIS MAN SAYS). "This was a lapse because during prayers they don't even let Christians enter. How did the suicide bombers come in so freely? This attack took place after prayers. This attack happened because of the negligence of security officials."
More than 100 people were reported to have been wounded in the explosions.
