The suicide bombing in Lahore, Pakistan, on March 27 is only one of dozens of attacks that have killed hundreds of civilians in Pakistan in recent years, with the Taliban or its splinter groups claiming responsibility for many.

More than 500 people have been killed in terror attacks since December 2014, when a team of nine Taliban gunmen stormed a crowded school in Peshawar. They killed 145 people in the deadliest single attack in the militant group’s history in Pakistan. The assault galvanized fragmented public opinion in Pakistan, as country of more than 180 million people, about how to deal with jihadist militancy.

In its wake, the government lifted a six-year moratorium on executions. In a harsh crackdown, more than 300 prisoners have been hanged in the last year under a new military judicial system.

But attacks – suicide bombers, planted bombs and raids by gunmen – have continued and are gathering pace. A look at major terrorist attacks in Pakistan since the assault on the Peshawar school in 2014 suggests that government officials, health workers and religious minorities continue to be frequent targets of attacks.
