When Sudan's President Omar al-Bashir attended a summit in South Africa in June 2015, he manged to leave the country - despite a high court order banning him from leaving because of an outstanding warrant for his arrest on charges of war crimes and crimes against humanity.

I was very disappointed.... about the unwillingness of South Africa to effect the arrest [of Omar al-Bashir].... I believe that in this particular case there was no ambiguity. The obligation of South Africa under the Rome Statute... was really clear. What they had to do is to arrest and surrender Omar al-Bashir to the ICC.

Fatou Bensouda, ICC chief prosecutor

The South African government did not stop Bashir from leaving and the incident is considered by many as a major setback to the cause of international justice.

The warrant had been issued by Fatou Bensouda, the chief prosecutor of the International Criminal Court (ICC).

In The Hague, Bensouda and her team of analysts and investigators try to bring those responsible for the most heinous crimes to justice. It is a seemingly endless process.

"What motivates us always is to have that opportunity to give a voice to the victims," she says.

But is it making a difference?

Critics say the international court has had such little impact that it is in danger of becoming obsolete. Others, however, point to the move just this last week by Palestinians to bring charges of war crimes against the Israeli government as an example how vital the ICC still can be.

Fatou Bensouda, the chief prosecutor of the International Criminal Court talks to Al Jazeera about Sudan's president escaping justice in South Africa, alleged war crimes in Palestine and Israel, and responds to those who challenge the credibility of the court.
