 South Sudan's basketball team came close to achieving one of the biggest shocks in sport on Saturday when they led a United States team made up of NBA stars with seconds to go in an Olympic warm-up game. Warren Bull has the story. It was an Olympic warm-up match for both sides and the US team read like an all-star selection, including Steph Curry and LeBron James. South Sudan are ranked 33rd in the world but led at half-time.
