Khartoum: Sudan's president has once again threatened to expel any international agency violating the country's laws.

President Omar Al Bashir addressed local leaders in the western region of Darfur where the UN's humanitarian arm has been denied access to a massive refugee camp following deadly clashes.

Sudan also accuses the UN-African Union peacekeeping force of harbouring five individuals from the camp wanted by the government.

Al Bashir told the gathering late on Saturday that any international organisation exceeding its mandate would be expelled.

The president in March 2009 expelled more than a dozen aid organisations from Darfur after he was charged with crimes against humanity by an international court for his role in the suppression of the Darfur rebellion.
