Church authorities have revealed that at least 172 villagers have died in a cholera outbreak that has triggered unrest in Indonesia's remote eastern Papua province.
Church aid workers in the Kamuu valley confirmed the victims had died from severe diarrhoea and vomiting caused by cholera, said Catholic brother Budi Hermawan from the Jayapura archdiocese.
The source of the outbreak, which began in April, was still unknown, but the disease appeared to be spreading via drinking water from a river and products in markets in the highland region, Hermawan told AFP by phone from Jayapura.
"In my view it's already too late, because people are very angry and they are desperate," he said.
The long delay had raised suspicions among local Papuans that the government was deliberately neglecting the outbreak and allowing them to die, Hermawan said.
Angry indigenous residents in Kamuu had attacked a settlement of migrants from other parts of Indonesia last week, destroying around a dozen houses, he said, adding that locals assume the migrants were to blame for the outbreak.
The head of the provincial health office, Bagus Sukaswara, denied the government had failed to tackle the health crisis, the local Cendrawasih Pos daily reported.
"We've been handling those cases since the start of May. Even if more cases show up again, we'll handle them," he was quoted as saying.
Indonesia won sovereignty over Papua, a former Dutch colony on the western half of New Guinea island, in 1969 after a vote among a select group of Papuans widely seen as a sham.
The region is among the least developed in Indonesia despite being home to rich natural resources worth billions of dollars.
