Hoang Xuan Vinh ended Vietnam's six-decade wait for an Olympic gold medal on Saturday, but he wasn't about to make a song and dance about his historic feat.

The 41-year-old military officer finally struck the Olympic bull's-eye for Vietnam to deny Brazil an opening-day title at Rio 2016.

Vinh fell into the arms of his coaches after his near-perfect final shot in the men's 10m air pistol. He had been dueling with Sao Paulo-born Felipe Almeida Wu, who had taken the lead after the penultimate round.
