Mine officials and a labor union say five miners are trapped deep underground at a South African diamond mine after a mudslide. The miners have been trapped since the early hours of Tuesday, according to the Congress of South African Trade Unions, an alliance of labor unions that includes the main mineworkers union. The congress said the miners were thought to be trapped around 800 meters (half a mile) underground. Ekapa Mining General Manager Howard Marsden, whose company operates the mine, said rescuers were drilling a hole to where the miners were to try and establish communication with the miners "or any proof of life.”
