Qatar's bid to host the 2020 Olympics is a chance to encourage female athletes across the Arabian Gulf region after years of sporting under representation, according to chief executive Noora al-Mannai."Not sending a female athlete to the Olympics (in the past) was because we didn't have anyone qualified," she told Reuters in an interview.The International Olympic Committee (IOC) has offered Qatar wildcard invitations for two female athletes to compete in the London Games later this year, swimmer Nada Arkaji and sprinter Noor al-Malki.
