“Testimonies of a massacre: Tula Toli” is one of the most remarkable films you are likely to see this year. Shafiur Rahman’s film contains scenes of jaw-dropping horror, and I mean that as a compliment. Shafiur traveled to Bangladesh at his own expense yet he has produced what is, without question, the most vivid record of the appalling horrors perpetrated against the Rohingya people by the Myanmar government. His work proves that one determined documentary maker working alone can best the mightiest broadcasters in the world.

I remember being struck dumb when he first showed me the extraordinary footage he had shot during the first days of the Rohingya exodus over breakfast one morning in a hotel in Cox’s Bazar. Shafiur has what I am tempted to describe as a “genius” for being in the right place at the right time, except that I know it is also the result of dogged hard work.

This is a film born of passion and determination. Night after night Shafiur would trek up through the rain to the border with Myanmar at huge risk to himself in order to do what only the greatest documentarians achieve – to bear witness to a crucial moment in history.

Seriously, don’t miss it!

This extraordinary film enters the wretched heart of Myanmar's genocidal aftermath. First on the scene, on Myanmar's border with Bangladesh, Shafiur Rahman reveals the devastating consequences of Myanmar's final assault on the Rohingya village of Tula Toli - told as villagers flee the most devastating massacre of the genocide. The film documents in forensic detail evidence of a planned and carefully orchestrated programme of annihilation revealed through the intimate testimony of Rohingya victims.'
