More than 50 people have died after landslides collapsed three artisanal gold mining wells in the Democratic Republic of the Congo.
The flood was caused by torrential rains.
The accident has taken almost 50 lives, as per the initial investigations, most of whom were young people trying to earn a living and support their families.
Alexandre Kamundala, deputy mayor of the nearby town of Kamituga, said no bodies had been recovered so far.
DRC's mineral-rich but volatile east faces regular attacks from a plethora of militias and rebel groups which operate freely in the region.
It's reported that several miners were in the shaft when it caved in following heavy rains.
"We went back there and found only the pit filled with water".
A two-day mourning period has been announced in the region to pay respects to the ones who lost their lives, and help the local authorities in rescue mission.
Hundreds of people gathered at the entrance to one of the tunnels, a video sent to AFP by the witness showed.
"When people wanted to get out, there was no way to because the water was pouring in at a great pressure", Nondo said.
The cause of the landslide is now under investigation.
Mining accidents are common, with dozens of deaths every year in mines where often ill-equipped diggers burrow deep underground in search for ore.
The mine was not located on the Kamituga gold concession owned by the Canadian miner Banro Corporation, the company's chief executive said.
Deadly collapses occurred earlier this year in Maniema and in Katanga, killing at least 18 people. DRC has huge reserves of gold, cobalt, copper and coltan.
It is the world's largest producer of cobalt, crucial for making the batteries used in mobile phones and electric vehicles.
Most Congolese earn their living in informal economic sectors such as makeshift mining.
