Indonesian rescuers are in a race against time to find dozens of people trapped after an illegal gold mine collapsed.

One person was killed in the incident, the country’s disaster agency said, after the landslide was triggered on Tuesday evening.

At least one person had been found dead and 13 others were injured in the Bolaang Mongondow region of North Sulawesi, a statement said.

“When dozens of people were mining for gold at this location, suddenly beams and supporting boards broke due to unstable soil conditions,” disaster agency spokesman Sutopo Purwo Nugroho said.

“It is estimated that as many as 60 people are buried under the landslide and rock debris.”

It was not immediately clear what condition the trapped miners were in.

The country has numerous unlicensed gold mining sites that have few, if any regulated, safety standards.

The central Indonesian government has banned such small-scale gold mining, although regional authorities often turn a blindeye to the practice in remote areas.

With little regulation, the mines are prone to accidents.
