Campaign group Amnesty International has urged Iran not to go ahead with a repeat execution for a drug smuggler who survived a botched hanging.

The condemned man, named as Alireza M, was found alive in a morgue after being hanged at a jail in the north-eastern city of Bojnord last week.

He is now being nursed to recovery in preparation for his repeat execution.

"The verdict was the death sentence, and it will be carried out once the man gets well again," an official said.
