Twenty-five years ago, the genocide in Rwanda resulted in the deaths of nearly a million people.

Most were Tutsis killed by Hutu militias. The children of victims and perpetrators alike grapple with the horrors of the past while hoping for a bette...

The chief prosecutor of a UN tribunal on Wednesday accused South Africa of failing to co-operate in the arrest of a fugitive sought over his role in the 1994 Rwanda genocide.

« Since August of last year, my office has been seeking urgent cooperation from South Africa in relation to the arrest of a fugitive located on its territory, » said Serge Brammertz, chief prosecutor of the UN's International Residual Mechanism for Criminal Tribunals.

Since 2010, the tribunal has handled outstanding and ongoing cases from the former International Criminal Tribunal for Rwanda (ICTR) that tried suspects in the 1994 genocide that killed around 800 000 people, mainly minority Tutsis.

« We have continually renewed our requests, and have repeatedly sought to engage directly with South African authorities, » he told the UN Security Council.

'You can't keep asking people to apologise': Rwandan president

Rwandan President Paul Kagame says a meaningful apology « must come from somebody who is apologising », during a press conference on the 25th anniversary of the genocide.

He said that after a year of « pro-forma responses », Pretoria had this week sent a message expressing its commitment to helping the court.

« I hope that this time it will deliver on this commitment immediately, » said Brammertz.

It is the first time that South Africa has been accused of failing to assist in the arrest of a fugitive sought by the court. In the past Kenya has been accused of protecting Felicien Kabuga, once one of Rwanda's richest men who is accused of financing the genocide.

Kabuga is one of eight fugitives that remain at large.

According to legal sources, it is former presidential guard head Protais Mpiranya who is believed to be hiding in South Africa.
