A Pakistani man who said that he was fifteen at the time of his arrest was executed at a prison in Sargodha in the eastern Punjab province on Tuesday.
Ansar Iqbal spent nearly twenty years on death row for the murder of a neighbor in 1994.
Pakistani courts would not look into the school and birth records of Iqbal which place his age between fourteen and fifteen years old at the time of his arrest.
Authorities said that these records are often flawed and not a legitimate source of evidence.
Pakistan has executed two hundred and thirty nine people since lifting the moratorium on the death penalty.
