Hannah won the People category at the Earth Photo Awards, with her series Barracks of Belgrade.
The series provides a bleak portrait of the refugee crisis in the Serbian city, where nearly 2,000 migrants are sleeping rough in a huge brick warehouse just behind the city’s main transport hub.
In 2017, the Serbian government requested that charities stop providing aid in order to discourage further arrivals.
Consequently, the resident migrants live amongst heaps of human excrement and, in temperatures of -16°C, burn toxic, creosote-soaked railway sleepers to try to keep warm.
