South Sudan says will not reverse plan to expel U.N. official

JUBA (Reuters) - South Sudan on Tuesday rejected a United Nations appeal to halt the planned expulsion of the world body's top humanitarian aid official in the country, saying he had regularly spoken out against the government.

U.N. Secretary-General Ban Ki-moon on Monday condemned the move to expel Toby Lanzer, deputy head of the U.N. Mission in South Sudan, and said the British-born envoy had been "instrumental in addressing the increasing humanitarian needs of conflict-affected communities" in South Sudan.
