The prime minister of Papua New Guinea said most of the refugees being held at the Australian-run detention centre in Manus Island are not genuine asylum seekers and are to be deported “within weeks”.

Describing most of the refugees as “economic migrants”, Prime Minister Peter O’Neill told ABC,

"Most of the other people who are in the processing centre: we're now talking to their governments and we will start repatriating many of them in a very short time."

Protests involving hundreds of asylum seekers erupted at the detention centre earlier this month, with many stating their asylum claims have not yet been processed.

Ian Rintoul from the Refugee Action Coalition told the BBC "[Mr O'Neill] is in no place to know whether they are [economic refugees] or not… There has been no determination assessment."

He went on to add that the news of deportation "undermines confidence that there is any respect for refugee law".

While the Egyptian government initially denied security forces were involved in the death, they have since stated an investigation into the killing has been opened.

Egypt’s Foreign Ministry though slammed “Western reports” of the deaths, saying “it is strange how such reviews failed to convey the reality, choosing to turn a blind eye to acts of killing, burning and horror conducted by supporters of the terrorist Muslim Brotherhood group”.
