An asylum seeker has been killed and at least 77 injured in the second riot this week at a detention centre in Papua New Guinea used to process asylum seekers, Australia's Immigration Minister said.
One person was in critical condition with a head injury and another sustained gunshot wounds during the clashes on a small island in impoverished Papua New Guinea.
Immigration Minister Scott Morrison says the riot began when detainees forced their way out of the centre, but refugee advocates insist it was sparked when Manus Island residents and police stormed the facility, attacking the asylum seekers.
The facility is part of Australian Prime Minister Tony Abbott's tough stance against asylum seekers but it has come under fire over human rights concerns.
