Five people, including a 15-year-old student, were killed when a gold mine collapsed in the central province of Nghe An Sunday, news website VnExpress reported.
According to witnesses, the accident happened at the mine in a forest of Dinh Hung Village, Tuong Duong District when the victims were removing rocks and earth.
Others managed to get away in time, witnesses said in VnExpress.
Vi Tan Hoi, vice chairman of Tuong Duong District's People's Committee, said rescuers and locals later recovered and identified the bodies.
Meanwhile, the site has been restricted for further investigation into the cause, according to Hoi.
However, it was still unknown whether the people entered the mine legally or not.
