Pakistan Bomb

Pakistan mosque blast: 100 confirmed dead in marathon search of rubble

The mosque is within a high-security zone and an investigation is under way into how the bomber got in.

The attack, one of Pakistan's bloodiest in years, has left scores more injured.

A Pakistani Taliban claim to have carried out the bombing was later denied by the militant group, which blamed it on a splinter faction.

In the past the Pakistani Taliban have refrained from claiming some attacks on mosques, schools or markets because they say they are at war with security forces and not the Pakistani people, but many doubt such denials.
