Human rights group Amnesty International has appealed for Singapore's Government to
declare a moratorium on executions.
A Melbourne man is currently on death row after being convicted for heroin smuggling.
According to Amnesty, Singapore executes more people than any other country relative
to its population size.
It renewed the call for Singapore to abolish the death penalty by citing unofficial figures that claim six people were executed by hanging last year.
Singapore's President, SR Nathan, is currently considering an appeal for clemency
in the case of Melbourne man Nguyen Tuong Van.
He was arrested with 400 grams of heroin at Changi Airport three years ago.
If the appeal fails, Nguyen will be hanged.
The 24-year-old has been helping a Federal Police investigation into an Australia-based international drug syndicate in the hope that cooperation would strengthen the pardon application.
