DAR ES SALAAM, Sept. 12 (Xinhua) -- A gold miner was killed on Tuesday and three others seriously injured after a mine collapsed in Tanzania's northwest district of Kahama in Shinyanga region, authorities said on Wednesday.
Anamlingi Macha, Kahama District Commissioner, said the three injured miners were in critical conditions.
"The mine collapsed and buried them. One victim came out unscathed," she said, adding that one of the three miners was rushed to Bugando Referral Hospital in Mwanza for specialized treatment.
Macha said the accident occurred on Tuesday night, after walls of the hole they were working in collapsed, burying them in the process.
Macha suspended all mining activities in the area pending investigations from the Minerals Department in the Ministry of Minerals.
Sengerema Yahululuka, an eyewitness, said when the incident occurred they immediately embarked on trying to rescue the victims but only managed to remove three of them.
"We are not sure whether there were other miners inside," he said.
