Australian Foreign Minister Alexander Downer on Thursday called on political opponents in violence-torn Timor-Leste to use peaceful means to resolve their differences.
A UN inquiry is expected to investigate if Timor-Leste Prime Minister Mari Alkatiri was behind the May 25 killing of 12 unarmed officers by rebel soldiers.
Australian Broadcasting Corporation radio reported on Thursday that Alkatiri has allegedly ordered to eliminate political opponents.
The radio quoted Downer as saying political difference must be solved lawfully in Timor-Leste.
"Those rebels and anybody else shouldn't try to resolve those issues outside of the constitution and outside the rule of law," he said.
"It would be completely unacceptable for the East Timorese or any other prime minister to try and act in a way which was illegal and outside of the confines of the constitution," he said.
Violence erupted in late April after the Timor-Leste government sacked 600 soldiers, or more than one third of the country's army, who protested against poor conditions and staged a strike. Foreign troops and police, mainly from Australia, Malaysia and New Zealand, are in Timor-Leste to help control the situation.
