The U.S. mining giant Freeport says gunmen fired at a company van near the world’s largest gold mine in a restive Indonesian province.

Company spokesman Ramdani Sirait said no injuries were reported in the ambush on Wednesday and police were on the scene investigating. He declined to give further details but said the shooting will not affect Freeport productions and operations.

Police could not immediately be reached for comment.

The mine run by Arizona—based Freeport McMoRan Copper & Gold, Inc. has been a target of violence since production began in the 1970s. Underdeveloped Papua province is home to a low—level separatist movement and is thousands of miles (kilometers) from Indonesia’s capital, Jakarta.
