The disaster happened at the Rubaya coltan mine in DR Congo’s North Kivu province
More than 200 people have been killed, including dozens of children, in a major landslide at the Rubaya coltan mine in eastern Democratic Republic of the Congo (DR Congo), officials reported on Wednesday.
The disaster struck the Kasasa mining area in the Masisi territory of North Kivu province on Tuesday, following torrential rains. Around 70 children were among the dead, the Ministry of Mines said, adding that a large number of injured have been evacuated to health facilities in Goma.
According to Actualite, the victims included mainly artisanal coltan miners who were working inside hand-dug pits, as well as traders who had set up small stalls near the excavation site.
“There were many of us in the shaft. The earth started to fall little by little… In a few seconds, everything collapsed,” a survivor told the news agency. Another miner noted they go down “without protection, without helmets, without engineers to check the ground’s stability” because they have no alternative way to earn money.
Search and rescue operations are underway with elementary tools as teams try to find survivors, Actualite reported.
The collapse at Rubaya follows a deadly landslide at the same site on January 28, when heavy rain triggered a collapse that killed more than 400 people, including miners, children and small traders.
Rubaya’s mines are a crucial source of coltan, a mineral used for electronic devices. The site produces around 15% of the world’s coltan and is under the control of the M23 rebel group, which has dominated the area since 2024.
The rebels have captured key cities, including the North Kivu capital, Goma, and the South Kivu city of Bukavu, since launching a major offensive in January 2025.
Landslides are a recurring threat in eastern DR Congo, particularly in the mountainous provinces of North and South Kivu, where prolonged heavy rains, deforestation, and informal housing increase vulnerability.
In early January, a heavy rain-triggered landslide struck the village of Burutsi in North Kivu province, killing at least 28 people and burying homes under mud and debris, local officials reported.
