The Bosnian war is the subject of a powerful documentary made by students from Mulberry Schoool for girls which is to be shown at the Barbican next week.

A team of six girls from the school in Shadwell researched the history of Bosnia’s civil war in the 1990s before being trained to use film equipment and then travelling to Bosnia last year to speak to survivors of the siege of Sarajevo.

They also attended the trial of war-time leader of Bosnian Serbs Radovan Karadzic at The Hague.

Following their visits, the students teamed up with film-maker Fiona Lloyd Davies to put it together. One year on the resulting film, Justice in Action, is to be given a public screening.

Afifa Gill, one of the students behind the film, said: “Being in a place where unthinkable crimes and unimaginable heartache took place, there are moments when you feel useless. But I felt confident that we can and we will make a difference.

“Even just storytelling, letting others know what happened in Bosnia, is fulfilling one of the wishes of the survivors that has been denied for too long: to be heard.”

Justice in Action is to be shown at the Barbican on Wednesday, September 26.
