Indonesia's government has distributed aid to West Papuans displaced by violence in the Central Highlands.
It comes after a report by a rights group claiming at least 139 people had died of starvation and disease in displacement camps.
Thousands are estimated to have fled the troubled Nduga regency, where rebels are waging war on the state.
Aid group Solidarity Team for Nduga has called for the provincial government to declare a humanitarian emergency.
Indonesia's military has denied the group's report, which said the deaths were in displacement camps in Wamena town.
But the Jakarta Post reports Indonesia's Social Affairs Ministry has sent $US53,000 worth of food, medical and educational supplies to the displaced.
Social Affairs Minister Agung Gumiwang said he had also instructed officials to visit the displacement camps to ensure the assistance was being distributed.
A medical team has also been dispatched to help people traumatised by the Nduga violence.
