The UNMISS say that it has recovered a number of weapons within and outside the PoC site.
Four AK-47 rifles, 22 AK-47 magazines, around 500 rounds of ammunition and 25 machetes (pangas) as well as military uniforms were found during a search.
In addition, RPG-7 was found approximately 70 metres from PoC.
The search was conducted by various UN agencies.
It confirms accusations by the SPLA that UN PoC sites are harbouring combatants who are hiding among innocent civilians.
Meanwhile, the South Sudan Ministry of Defence has been asked to secure all routes out of Juba.
The call was made on Saturday after the meeting of the ruling party’s Politburo.
The government has restricted travel out of Juba in the last few weeks because of number of deadly ambushes on the roads against civilians.
It said it would be irresponsible to let people travel into uncertainty.
The government said that once the roads are secured civilians can move freely wherever they may wish.
While meeting UN Secretary General Ban Ki Moon on the sidelines of 27th AU Summit in Kigali, Ugandan President Yoweri Museveni proposed a regional protection force be sent to Juba to protect deputy president Riek Machar.
He also called for a complete ceasefire in Juba to stop fighting as the country prepares for elections.
