Thirty years after the war in Bosnia, survivors and their descendants find themselves permanently displaced in their own country. BBC reporter Lauren Tavriger visits the Tuzla region where families fleeing atrocities, including the Srebrenica massacre, have been living for decades in makeshift settlements originally designed as temporary. She talks to families about their experience, discovering why traumatised people are still living in a state of internal exile and reports on controversial efforts by the Bosnian authorities to clear camps and rehouse their inhabitants.
