Iran's judicial authorities have previously denied accusations of juvenile executions, but according to HRW, the country has executed at least 10 juvenile offenders since 2009.
Last November the governor of Oregon, John Kitzhaber, put a moratorium on all executions and in April Connecticut became the fifth state in as many years to abandon capital punishment altogether.
Writing before the announcement that Australia was withdrawing its ambassador, he predicted the executions would affect Australians' perceptions of Widodo for the rest of his tenure, but warned against such a step.
We should withhold bilateral visits by ministers while the foreshadowed executions continue or for the rest of the year," McCarthy wrote for the Australian Strategic Policy Institute.
"Some prayed, but some who had prayed before they arrived would say: 'There cannot be a God if Auschwitz exists.'" For six weeks, Piechowski was set to work carrying corpses after executions.
A spokesman for Prasetyo, Tony Spontana, told Guardian Australia the executions would be after the Asian-African conference in Jakarta from 19 to 24 April, but could not confirm a timeframe beyond that.

All 35 executions were carried out by just seven states, and of those 80% were accounted for by just three states – Texas, Missouri and Florida.
Only Missouri bucked the trend – it lethally injected 10 prisoners compared with just two the previous year, as it forged ahead with an aggressive new drive to carry out executions at a rate of almost one a month.
Arizona added its name to the grisly list of death penalty states carrying out botched executions in July when it took almost two hours and 15 doses of drug to kill Joseph Wood.
Even in Texas, long ground zero of the death penalty in America, the number of executions sharply declined this year, from 16 in 2013 to 10 in 2014.
