Swim Champ Who Saved a Sinking Boat

Sarah Mardini and her younger sister Yusra are both world class swimmers from Syria. When they were trying to flee their war torn country the sisters' talent saved the lives of 18 people when their boat got into trouble in the middle of the Mediterranean sea. They pushed the boat to safety and Sarah tells Matthew Bannister what that experience was like. Image: Sarah Mardini speaking to volunteers in Greece Credit: Arif Nurhakim
