More than 50 people convicted of terrorist offences in Pakistan arefacing imminent execution after President Mamnoon Hussain rejected their mercy petitions, officials say.
The president's move means that some executions can take place across the country at any time.
Six people executed have been executed since a moratorium was lifted in the wake of a Taliban school massacre.
Hundreds more executions could follow in the next few months, reports say.
The Taliban attack in Peshawar killed 141 people and caused outrage across the country, with renewed calls for convicted terrorists to face capital punishment.
Human rights groups say that Pakistan has the world's largest number of death row inmates, with more than 8,000 people awaiting execution.
Amnesty International on Monday said that moves to execute 500 people in the coming weeks were "deeply disturbing" and would do nothing to protect civilians from the Taliban.
Rights campaigners in Pakistan say that many of those on death row are not connected with terrorist groups.
