Olympic athletics: Qatari female sprinter Noor Al-Malki suffers injury

An historic run for Qatar's first female Olympic track athlete, Noor Al-Malki, was ended by injury.

The 17-year-old failed to finish her 100m heat after appearing to pull a hamstring as she came out of the blocks at London's Olympic stadium.

Al-Malki, dressed in a maroon running suit and cap, limped off the track with the help of officials after bursting into tears.

She is one of four females competing for Qatar in London.
