Iryna Bui took gold in the women's middle distance standing biathlon, with Oleksandra Kononova winning silver and Liudmyla Liashenko bronze.

Team spokeswoman Nataliia Harach said: "She was very upset and couldn't take part in the race."
After winning silver, Kononova said: "All my thoughts, my heart and my soul is with my family and with my child.
"Emotionally it's very difficult to focus and to concentrate on the race and the competition, so this is the most difficult Paralympic Games for me."
