The bomber struck shortly before afternoon prayers, when the mosque in Peshawar’s bustling Police Lines district would be at its busiest. Hundreds of people, including many police officers, were inside as the device detonated, creating a blast so strong the roof and a wall collapsed and 100 people were killed.
The attack last Monday was among the worst in years to hit Peshawar, a city in north-west Pakistan that has been ravaged relentlessly by deadly terrorist violence over decades.
