Indonesian police have shot dead two members of the West Papua National Committee (KNPB), a separatist group, campaigning for West Papuan independence.
Hubertus Mabel, 30, and Natalis Alua were killed, bringing the toal of KNPB members killed this year to 22.
A police post was later burnt down by unidentified men, which saw retaliation by police who attacked a house used as a tribal council and burnt it to the ground.
People in the province of West Papua have been claiming independence from Indonesia since it became part of the country in 1969.
