In the 18 months that Franz Rauchenstein has headed up Red Cross relief work in South Sudan, he has seen the country brought to its knees by conflict.
The humanitarian situation has deteriorated and gross human rights abuses – sexual violence, abductions, executions – have lent the conflict a particularly nefarious edge.
Attacks against aid workers, including several against the International Committee of the Red Cross (ICRC), have become all too regular.
Rauchenstein, who has been working with the ICRC for 22 years, knows that his job was to help alleviate the vast humanitarian crisis in the world’s newest nation.
His sense of dismay at the current situation is palpable.
