The faces of some of those awaiting execution and others who have already been put to death
Last December Pakistan lifted a seven-year moratorium on executions in response to a deadly Taliban attack on a school in Peshawar. Since then at least 157 people have been put to death - many of whom were not convicted of terror offences.
The BBC's Claire Brennan looks into some of their cases and examines the reasons behind Pakistan's dramatic shift in death penalty policy.
Who is on death row?
Shafqat Hussain's parents have not seen their son for over a decade
Pakistan is believed to have the largest number of death row inmates in the world. Some 8,200 prisoners are awaiting execution - many of whom have been in jail for over a decade.
The vast majority are men, however there are some women - most notably theChristian Asia Bibi who was convicted of blasphemy in 2010.
The mother-of-five was accused of insulting the Prophet Mohammed and sentenced to death, despite her insistence that the evidence against her had been fabricated.
Some 27 crimes carry the death sentence in Pakistan, including terrorism, rape and adultery. Figures from the Justice Project Pakistan, show most people facing execution have been convicted of a "lethal offence".
However, in Punjab, for example, 226 prisoners were placed on death row for "non-lethal offences".

There are also concerns that up to 1,000 people convicted as juveniles are facing execution - something that is illegal under international law. But proving your age in Pakistan can be difficult, particularly in poor communities where many births are not registered.
Aftab Bahadur was put to death on Wednesday, even though human rights campaigners say there is evidence which proves he was a minor when he was convicted of murder in 1992. They also say he was tortured into giving a confession.

On Tuesday the execution of Shafqat Hussain was postponed by the Supreme Court just hours before he was due to be hanged.
He was found guilty of killing and kidnapping a seven-year-old boy in 2004 - but his lawyers also maintain he was underage when the alleged crimes were committed.
Why was the moratorium lifted?
The bloody scenes in Peshawar sparked calls for the government to do more to target terrorists
The massacre of 132 children in Peshawar last December was the catalyst for the reintroduction of the death penalty.
Amid public anger, Prime Minister Nawaz Sharif announced the moratorium would be lifted for terror convicts - before eventually resuming executions for all death penalty offences.
The move was condemned by the United Nations and human rights campaigners who warned it would do little to impede the Taliban.
"The government is touting executions as the way of tackling the country's law and order problems," said Maya Pastakia, a Pakistan campaigner for Amnesty International.
"But there is no compelling evidence that the death penalty will act as particular deterrent over and above any other form of punishment. A suicide bomber won't be deterred by the death penalty."
She believes lifting the moratorium was "a lazy response" to dealing with the huge numbers of people on death row.
Saulat Mirza was executed in May over a political killing
"We have seen a conveyor belt of executions. People who were implicated in terrorism crime, as well as people convicted for straight-forward murder, manslaughter and kidnapping.
"The government seems entirely intransigent on this issue."
Who has been executed and why?
Two Baloch hijackers were executed for storming a Pakistan International Flight
The first series of hangings took place at Faisalabad jail in December - and are now almost an everyday occurrence across the country.
Many prisoners have been put to death for terror offences, including three Baloch insurgents who hijacked a passenger plane in 1998.
Others were found guilty of political killings, like Saulat Mirza - a former worker for the Muttahida Qaumi Movement (MQM) who was convicted of murdering the head of Karachi's power utility service.
But some cases have attracted attention over concerns about the legitimacy of their trials.
Shafqat Hussain "was at worst a common criminal", according to his lawyer Sarah Belal, yet his case was processed by an anti-terrorism court.
"It goes to the heart of all the problems with the judicial system," she told the BBC. "He belongs to a poor community. He was not a terrorist."
