Jakarta – An armed group launched yet another attack at around midnight on Tuesday near the mining site of PT Freeport Indonesia in Mimika, Papua.

Mimika Police deputy chief Comr. Mada Indra Laksanta said the group attacked a patrol vehicle operated jointly by Freeport's Security Risk Management and the National Vital Object Taskforce, comprising police officers and soldiers.

"[The security officers] used the No. 15 Route Patrol vehicle," Mada said Wednesday in Mimika, as quoted by tempointeraktif.com.

He added that the attack took place at the 35th mile of the Timika-Tembagapura road, adding that no one was injured, although a bullet penetrated the patrol car driver's helmet.

Meanwhile, as of Wednesday morning, the road connecting Amamapere Port and Tembagapura, the Mimika district where Freeport mines are situated, was still being blocked by protesters, halting food and fuel supplies to the mine site.

Thousands of Freeport workers in the province have launched strikes and protests – one of them fatal – since last month, demanding a pay rise. The government is scheduled on Wednesday to again mediate negotiations between Freeport's management and the workers.
