Officials say about 15 gunmen have attacked a police station in Indonesia's restive Papua province, killing three officers and wounding two others.

Local police spokesman Col. Patrige Renwarin said the assailants attacked the station in Sinak town in the mountainous district of Puncak late Sunday while the victims were watching television.

He said the attackers took away seven assault rifles and a crate of ammunition.

President Joko Widodo is planning to visit Papua, Indonesia's easternmost province, to celebrate the New Year.

A low-level insurgency for independence has continued in the region since it was transferred from Dutch to Indonesian rule in 1963.
