Doctors kicked off Nauru say the boat people Australia put on the island nation are suicidal and "devastated" children have lost all hope.
The Nauru government last week suddenly kicked MSF off the island, which has a population of about 13,000 people, after it had been working there since November 2017.
Home Affairs Minister Peter Dutton said MSF was not involved in providing medical services to immigration detainees on Nauru.
But MSF later confirmed the memorandum of understanding with the Nauruan government was clear that refugees and asylum seekers would be provided services.
"Beneficiaries of the project: People suffering from various mental health issues, from moderate to severe, members of the various communities living in the Republic of Nauru, including Nauruan residents, expatriates, asylum seekers and refugees with no discrimination," the agreement stated.
