PARIS — Algerian boxer Imane Khelif has won a gold medal Friday at the Paris Olympics, emerging a champion from a tumultuous run at the Games where she endured intense scrutiny in the ring and online abuse from around the world over misconceptions about her womanhood.

Khelif beat Yang Liu of China 5:0 in the final of the women's welterweight division, wrapping up the best series of fights of her boxing career with a victory at Roland Garros, where crowds chanted her name, waved Algerian flags and roared every time she landed a punch.
