Mimika legislative council member Karel Kwijangge said security reasons were the main consideration for the immediate funeral.

"For the sake of the interest of Papuan people the sooner is the burial the better," Karel said on Sunday.

Karel said there was no agreement yet about whether Kelly's remains would be buried in an area near Moses Kilangin airport or in a public cemetery.

As of Sunday afternoon, around 400 people were seen packing the legislative council hall to pay last respect to the late rebel leader. Dozens of police officers stood on guard outside the building.

Police personnel shot Kelly to death during a raid on his house in Kuala Kencana area in the town of Timika early on Wednesday.
