University students and human rights activists staged a rally on Sunday in West Papua demanding Indonesia's President Joko Widodo fulfil his vow to settle a human rights violation case.
Five people, including four high school students, were allegedly shot and killed by Indonesian soldiers on 8 December 2014, during a protest in Paniai.
The Jakarta Post reports that five years later, demonstrators gathered at the Sorong urban park and put up leaflets that read: "We demand proof, not promises".
They called for the prosecution of those responsible for the shooting. The protesters chanted: "Papua does not need [more] security [personnel]. Papua only needs justice."
Mr Widodo had promised to resolve the case in a speech delivered a few weeks later in Papua's provincial capital of Jayapura on 27 December, 2014.
But the field co-ordinator of Sunday's protest, Ambrosius Klangit, said Papuans and the victims' families were still waiting for Mr Widodo to fulfil his promise.
