A refugee watchdog says it has serious concerns over an Iraqi hunger striker on Papua New Guinea's Manus Island
The Refugee Action Coalition says the 31 year-old man has been on hunger strike for 53 days and has lost 19 kilos in weight.
A spokesperson for the group Ian Rintoul says the man can no longer walk and is in a wheelchair.
He says the man is being mistreated by being held in isolation and torture techniques are being used to force him to eat and drink.
Thousands of asylum seekers are being detained in camps on Manus and in Nauru under Australia's offshore refugee processing policy.
