The South Sudanese government has accused the UN peacekeeping mission in the country of hiding rebels and their arms at their camps, which are giving shelter to over 70,000 civilians.
The country’s president, Salva Kiir has hit out at the UN, saying it acted like a “parallel government” in South Sudan.
"We did not know that when the Unmiss was brought to South Sudan, they were brought as a parallel government with the government in South Sudan," Kiir said.
"They fell short of naming the chief of the Unmiss as a co-president of the Republic of South Sudan.
"If that is the position of Ban Ki-moon, he should make it clear that he wants the UN to take over South Sudan."
Kiir wants the government to be allowed to enter UN camps to search for rebels and troops, after the country’s information minister tried on Sunday to force access to a UN base, saying armed rebels were hiding there.
The Unmiss spokesperson said UN was impartial and had a "zero tolerance policy towards weapons" in its camps.
"When people come to our sites with weapons, uniforms - military equipment of any sort - it has been given to us to make sure that the site have a civilian nature," Ariane Quentier told the BBC's Focus on Africa radio programme.
"It is very clear that we have a number of people that we cannot check individually but just the mere fact that we have 70-80% women and children is a clear indication that we're not sheltering rebels," she said.
