Vietnamese state media say a shortage of the drug used in lethal injections has halted the execution of hundreds of prisoners on death-row.
Tuoi Tre newspaper on Tuesday quoted Vice Public Security Minister Dang Van Hieu as saying that the executions of more than 400 death-row prisoners have not been able to go ahead over the past year due to the shortage of the drug.
The report did not name the drug, but said it had to be imported. Hieu said this "proved to be difficult."
Vietnam changed its execution method from firing squad to lethal injection last July, but no inmates have been executed since.
