The execution of death row prisoner Richard Glossip in Oklahoma has been halted after the State's governor stepped in. Mary Fallin has issued a 37-day stay of execution to address legal questions about Oklahoma's execution protocols and the chemicals used for lethal injection.
A prisoner in Oklahoma is due to be put to death in the next few minutes for a crime he insists he didn't commit.
Richard Glossip was convicted of hiring a murderer, almost entirely on the testimony of the man who carried out the killing.
Today the pope urged the state's governor to spare him.
Ray Krone's a former death row inmate who now campaigns against the death penalty: "We're human we make mistakes we get it wrong, there should not be a punishment that cannot be later reversed.
"In this case again clearly there are so many questions.
"Mr Glossip is one of those people that is not reasonable doubt.
"There is too many questions there to be taking this man's life."
