Six people have been killed and 41 wounded during clashes between members of two tribes in Indonesia's Papua province, police say.
The clashes erupted after members of the Kimyal tribe armed with arrows, bows and machetes attacked Yali tribesmen in Yahukimo district on Sunday, Papua police spokesman Ahmad Musthofa Kamal said.
It was not clear what sparked the attack, Kamal said. About 1000 people sought refuge at a local police station in the wake of the attacks, he said.
Local media reported that the attack was triggered by rumours that a politician from the Kimyal tribe who died recently of a heart attack had been killed by rival tribesmen.
Papua, on the western half of New Guinea island, has been the scene of a separatist insurgency since the 1960s.
The mainly Melanesian region was incorporated into Indonesia in a controversial UN-administered ballot in 1969.
