Two more athletes fail dope tests

A North Korean shooting medallist and a Vietnamese gymnast have been kicked out of the Olympic Games after testing positive for banned substances.

Shooter Kim Jong Su was stripped of his silver medal in the 50m pistol and bronze in the 10m air pistol, the International Olympic Committee said.

Gymnast Thi Ngan Thuong Do finished in 82nd in the women's floor exercises.

The incidents follow the expulsion on Monday of Spanish cyclist Maria Isabel Moreno, who tested positive for EPO.
