Indonesian Police have allegedly committed a number of atrocities on the eve of West Papuans observing the Easter holidays, allegedly murdering at least five civilians — including the reported death of a minor — with other sustaining serious injuries in what was described as "colonial rampage".

Free West Papua campaigners have reported an Indigenous Papuan police officer was allegedly killed by an unknown assailant in front of the Ebenezer Church, located in Moanemani village in the Indonesian administrative division of Dogiyai Regency on traditional Papuan lands.

In response, police allegedly opened fire across the Moanemani market.

Reports suggest the operation quickly spread to the neighbouring Ikebo village, as police were said to have fired indiscriminately into the homes of Ikebo residents.

It is unknown how many people were shot in total, however residents Ester Pigai, 60, Yosep You, 20, Siprianus Tibakoto, 19, Angkian Edowai, 19, and Martinus Yobee, 14, were found deceased.

Images of the deceased victims have been distributed online, which National Indigenous Times has chosen not to show.

Maikel Waine, 14, was also severely wounded, reportedly possibly dead, after suffering a gunshot wound to the left side of his chest which also penetrated his left shoulder.

Maikel Pekei, 11, was also seriously injured, shot in the upper chest. He was left in a critical condition and is still being treated in hospital.

Church sources on the ground have reported an ongoing battle is being waged between security forces and Papuan youths, who are attempting to block the road into Moanemani, scattering logs and rocks across it to prevent Indonesian military reinforcements reaching the village.

A joint military and police armed unit was also reported to be en route to the area ahead of Easter.

United Liberation Movement for West Papua interim chairman, Benny Wenda, called on Indonesia to withdraw their occupying forces.

"Deploying the military now will only bring more bloodshed," he said in a statement from exile in London.

"West Papuan civilians are the victims of (President) Prabowo's ongoing military escalation, which has spread across Yahukimo, Intan Jaya, Paniai, Maybrat, and now Dogiyai (regencies).

"What the carnage in Dogiyai demonstrates is that Indonesia views that all West Papuans are legitimate targets.

"Elders, women, and children: no one is safe from the murderous vengeance of the Indonesian security state.

"The massacre triggered a wave of internal displacement, as terrified civilians have fled into the mountains and surrounding villages.

"Indonesia's actions in Dogiyai are both a crime against humanity — a grave act of colonial violence — and a breach of international law.

"Shooting indiscriminately into homes and a public market is a form of collective punishment, while the intentional killing of civilians is a war crime, prohibited under the Geneva convention."

Mr Wenda reiterated a call for Indonesia to allow the United Nations High Commissioner for Human Rights to visit the West Papuan territory.

More than 110 sovereign countries — a clear majority of the UN member states — are demanding Indonesia is held to account.

However the Indonesian government has continued for the past seven years to refuse scrutiny from UN officials in what the Free West Papua movement has long deemed to be occupied Indigenous land.

"Dogiyai is not an isolated incident - every day brings a new atrocity," Mr Wenda said.

"How long will the world allow this (occupation) to continue before Indonesia is made to suffer genuine diplomatic consequences for their refusal?

"I direct this particularly at Pacific leaders - how long will you allow Indonesia to spill Melanesian blood before taking a real stand against this genocidal occupation?

"How many Papuans must die?"

The alleged massacre occurred less than a fortnight before the Indonesian military arbitrarily arrested and allegedly tortured a separate West Papuan civilian in the Maybrat Regency.

Yusuf Sory was detained by military forces amid a gunfight alongside the West Papua National Liberation Army.

Mr Sory's whereabouts still remain unknown, with Free West Papua campaigners fearing he is dead.

A video, circulated online, has showed Mr Sory tied to a tree while being interrogated and beaten up by Indonesian soldiers.

The alleged torture incident has prompted a renewed humanitarian crisis in Maybrat Regency under reports all public activities had come to a standstill, residents were unable to leave their homes, with the community going without food for multiple days.

Mr Wenda condemned what he termed "evil and cruel actions committed by the occupying military".

"These incidents have happened for 60 years but only now, because of social media and citizen journalists, can the world see what life is really like for West Papuans," he said.
