DARDUR - Aid workers fear for Darfur camps after the ICC decision  The UN secretary general has urged Sudan to rethink its decision to expel aid groups from its Darfur region.

Ban Ki-moon said the decision could cause "irrevocable damage" to the humanitarian operations in Sudan.

The order came after the International Criminal Court (ICC) issued an arrest warrant for Sudanese President Omar al-Bashir over alleged war crimes.

Mr Bashir is charged with war crimes and crimes against humanity

Sudan's deputy permanent representative to the AU, Akuei Bona Malwal, told the BBC that the agencies had been "deemed to have worked beyond the permit that was given to them".

The arrest warrant has been greeted by human rights groups as a step towards justice for the 300,000 people the UN says have died and the nearly three million who have fled their homes as a result of the conflict in Dafur.

But it has been criticised by many in Sudan and by groups including the AU and the Arab League, which have agreed to send a joint delegation to the New York to press the UN Security Council to delay the indictment.
