16 year old Sarah (her name changed to protect her identity) visits Lalish, the site of the tomb of Sheikh Adi bin Musafir, a prominent figure in the Yazidi religion. Sarah is from Iraq's Yazidi community. She was captured by Islamic State (IS) fighters and held for over five months. The Yazidis are an ethno-religious group whose largest communities until recently lived in northern Iraq. Since the emergence of Islamic State (IS) in Iraq and neighbouring Syria, the group has been increasingly targeted by Islamist forces which have killed thousands and enslaved thousands more women.
