At least two miners were killed when the walls of a gold mining site collapsed in Nyatike, Migori.
Four others were rescued and rushed to hospital in critical condition.
The incident happened Thursday afternoon as a group of miners ventured into about 200 feet-deep site for the mineral, police said.
Witnesses said there were six miners in the tunnel when the walls collapsed killing two on the spot.
The deceased were identified as Kennedy Kapis, 45 and Jared Aloo, 35.
The incident came a day after a miner died when a gold mining site collapsed and trapped them in Lirhembe village, Ikolomani, Kakamega.
One was injured and rushed to hospital in serious condition following the Wednesday evening incident, police said.
The victims were among a group of miners at the gold mining site when the walls collapsed trapping them.
The miners were about 200 feet in the tunnel when the incident happened, other victims said.
The incident comes weeks after at least three gold miners died after the walls of an underground mine collapsed in Manyatta village, Vihiga.
Police said two others escaped with injuries in the incident. They were pulled out alive and rushed to hospital.
Another miner had a week ago died at a gold mine site in West Pokot.
Officials however say the tunnels where the miners venture are unsafe for their operations.
The officials said the miners were using heavy machines to crush stones in their artisanal activities, overlooking the environmental impact.
