Officials say that a bomb blast outside a church in the Pakistani city of Peshawar has killed at least 60 people and injured more than 100 others.
Reports say two suicide bombers blew themselves up as people were coming out after Sunday Mass.
The victims were said to include women and children.
Islamist militants have been blamed for previous attacks on Pakistan's Christians, who make up about 1.6 percent of the country's mainly Muslim population. No group has admitted carrying out the attack.
Witnesses said they heard two blasts, the second more powerful than the first.
About 500 to 600 people were believed to have been inside the church at the time.
Grieving relatives have gathered to identify their relatives.
