According to details, the convict Murad Ali was executed after a formal medical examination in Sargodha District Jail.
Murad was convicted of killing a husband wife duo over an old enmity.
Pakistan lifted the moratorium on death penalty on Dec. 17, a day after Pakistani Taliban gunmen attacked Army Public School in Peshawar and killed 134 students and 19 adults.
The moratorium, in force since 2008, was initially lifted only in terrorism cases. But the government extended the order in March, directing provincial governments to proceed with hangings for all death row prisoners who have exhausted their appeals and clemency petitions.
