Twin suicide bombings outside a Christian church in Peshawar, Pakistan, killed at least 78 Sunday.

The bombings are believed to be the deadliest attack on Christians in Pakistan ever.

The two bombers blew themselves up outside a 130-year-old church following mass.

About 600 people had attended services and were outside receiving free food that was being distributed when the bombs went off, according to The New York Times.
