When local people discovered the accident, they could only rescue seven people, who were heavily injured. They were brought to the Tuong Duong district hospital.
Three others died since they were buried too deep. The dead victims include three men of 40, 22, and 18 years old from Thanh Chuong district, Nghe An province.
Local police said that the mine had collapsed because it was a vault. The local government also said that this is an illegal mining case.
In May 2011, an illegal gold mine collapsed, killing five people, also in Tuong Duong district.
