For the first time in history, the Saudi Arabian squad will include women – one competing in judo and the other in 800m run. Brunei and Qatar will also break with tradition to include female athletes. Then there's Zamzam Ali Farah of Team Somalia, who had to endure intimidation from al-Shabab militants while training in Mogadishu for the 800m:
"The Shebab kept threatening me, they wanted to stop me from reaching my dreams," said Farah. "It was hard since that meant we were forced to have our training indoors."
