Riot at nickel plant in Indonesia kills two

Two workers including a Chinese national were killed at a nickel smelting plant in Indonesia at the weekend after a riot broke out during a protest over labour conditions, officials said Monday.

The clashes broke out Saturday evening at the facility on Indonesia's Sulawesi island operated by PT Gunbuster Nickel Industry (GNI), a local unit of China's Jiangsu Delong Nickel Industry.

The island is a hub for the mineral-rich country's production of the metal, which is used for electric vehicle batteries and stainless steel.

A 30-year-old Chinese worker and an Indonesian worker at the facility were killed, Central Sulawesi police spokesman Didik Supranoto told AFP, without giving a cause of death.

Local employees angry at their working conditions and pay held a one-day strike that resulted in clashes with security officers when they tried to enter the premises and set fire to heavy machinery and vehicles, he said.

"There was a stir because they forced their way into PT GNI's area. Security tried to drive them away but they managed to get in," the police official said.

"They did anarchist actions -- arson and damage. From there, clashes occurred between workers who went on strike with workers inside."

At least 71 people were arrested after the incident, of whom 17 were suspected of causing damage during the unrest, Supranoto later said in a statement.

Hundreds of officers were deployed to the smelting facility after the riot broke out, local media reported.

"We express our deep condolences about the demonstration that ended in chaos... because it did not only impact the company but also the surrounding community," GNI said in a statement.

It said the company and police were investigating the protest and deaths.

Operations at the facility -- which was inaugurated by President Joko Widodo in 2021 and has an annual production capacity of 1.8 million tonnes -- have been stopped after the incident, Supranoto said.

Indonesia wants to become a global production hub for electric batteries, and Sulawesi island's nickel reserves, crucial to that strategy, have drawn interest from Beijing and some of the world's biggest carmakers.

US-based electric vehicle maker Tesla has reportedly expressed interest in potential EV battery investments in Indonesia.
