The city of Mostar in Bosnia-Herzegovina was ruined by the war that followed the breakup of Yugoslavia in the 1990s. People of different ethnicities - who'd lived together happily for years - started fighting each other, and the river that divides Mostar became an unofficial border between Bosniaks and Bosnian Croats. Ten years ago, one man had a plan for bringing the two sides closer together. Oha Maslo set up the Mostar Rock School to teach kids from both banks of the river, and bit by bit it's changing attitudes.
