Two employees of US mining giant Freeport were slightly injured when gunmen fired at a company van near the world's largest gold mine in a restive Indonesian province, an official said Thursday.
Company spokesman Ramdani Sirait said the ambush Wednesday did not affect operations at the mine.
The two employees were treated for minor cuts caused by broken glass, Sirait said in an email message.
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.
