Jayapura. At least 17 people were killed in a clash between two groups of civilians in the district of Puncak Papua on Sunday.

It was the first such incident in the newly established district, which had been part of Puncak Jaya district. It is the deadliest brawl to hit the restive province of Papua in recent years.

Papua Police spokesman Sr. Comr. Wachyono said the brawl, which occurred at about 7 a.m. in the district capital, Illaga, might have been caused by political frictions.

Based on initial information, Wachyono said, the clash occurred between supporters of Elvis Tabuni, the speaker of the Puncak Papua legislative council, and supporters of Simon Alom, who led the transitional process during the establishment of the district.

“As a result of the brawl, 13 supporters of Elvis Tabuni were killed and four people from Simon Alom’s side died,” he said.

Puncak Papua is holding its first election this year and both Elvis and Simon are said to be preparing to run for district head.

The position has been vacant since May after the then-district head, Recky Ambrauw, was arrested over allegations he falsified a gubernatorial decree on his appointment to the position.

Wellem Wandik , chief of the Puncak Jaya regional development agency, confirmed that a brawl took place on Sunday but could not provide further details.

“I am not in Puncak Papua, but according to reports I have received, yes there was a brawl. That is all I know,” he said.

Wachyono said dozens of people were badly injured and a number of houses, buildings and vehicles were set on fire.

“The clash started in front of the council office but the fighting continued and affected residential areas,” he said.

Wachyono added that the police were struggling to obtain more information on the brawl because of the remoteness of the area and poor infrastructure.

The area is a one-hour flight from the Papua capital, Jayapura, and is inaccessible by land. Charter flight operators only fly once a week from Jayapura to Illaga.

The police officer said that the best way to communicate with the area was through satellite phones, which only a handful of people in the area have.

“We received the news through the police’s SSB,” he said, referring to a single-side band radio.

Wachyono said the police had not been able to establish what had triggered the clash, or determine the exact chronology of the incident.

On July 21, an Indonesian solider was killed in a suspected ambush in Puncak Jaya.
