The deadliest attack on Christians in Pakistan has brought protests in several cities.
More than 80 people are known to have died after two suicide bombers blew themselves up outside an Anglican church in Peshawar on Sunday. Three days of mourning have been declared.
Demonstrators vented their anger at the government, accusing it of failing to protect minorities.
A militant group linked to the Pakistani Taliban claimed responsibility, saying it would continue its attacks on non-Muslims.
People blocked streets in Islamabad and elsewhere, with more protests expected.
Burials have been taking place in Peshawar, the northwestern city surrounded by tribal areas often controlled by militants.
Pakistan’s Christians number about two percent of the population and are among the country’s poorest.
The politician Imran Khan, whose party leads the provincial government in Peshawar, said the attack was a deliberate attempt to ruin peace talks.
