An Iraqi doctor being held in an Australian detention centre was refused permission to attend an award ceremony at which he was to be honoured for an article he wrote on the psychological damage caused by incarceration.
Dr Aamer Sultan fled persecution under Saddam Hussein's regime after treating Sh'ite Muslim rebels injured in fighting with government forces.
He arrived in Australia via Turkey in 1999 and was immediately sent to Villawood Detention Centre in Sydney, where he has been held since.
Australia's Human Rights and Equal Opportunity Commission gave him the award for an article he wrote in this month's Medical Journal of Australia on the health of asylum seekers.
Dr Sultan was refused permission to attend the award ceremony on Sunday by the Immigration Minister, Philip Ruddock, who has written to the journal to complain about what he says are factual errors in the essay.
'Detention is not arbitrary, it is humane and is not designed to be punitive,' Mr Ruddock said.
