A day after terrorists killed 141 people in an attack on a school in Peshawar, Prime Minister Nawaz Sharif has approved abolishment of moratorium on the execution of death penalty in terrorism-related cases. <br /> <br />The assault on the army-run school in the northwestern city of Peshawar, the deadliest terror attack in Pakistan s history, has triggered widespread revulsion. <br /> <br />Political and military leaders have vowed to wipe out all the terrorists, who have killed thousands of ordinary Pakistanis in recent years. <br /> <br />"The prime minister has approved abolishment of moratorium on the execution of death penalty in terrorism-related cases," an official from Sharif s office said. <br /> <br />Earlier on Tuesday, Army Chief General Raheel Sharif had advised the Prime Minister to hang all the convincted terrorists, sources told. <br /> <br />Hanging remains on the Pakistani statute book and judges continue to pass the death sentence, but a de facto moratorium on civilian executions has been in place since 2008. <br /> <br />Only one person has been executed since then, a soldier convicted by a court martial and hanged in November 2012. <br /> <br />Rights campaign group Amnesty International estimates that Pakistan has more than 8,000 prisoners on death row, most of whom have exhausted the appeals process.
