UN optimistic after meeting with S. Sudan ministers The UN Security Council has met with ministers in South Sudan to convince them of the need for 4,000 additional peacekeepers. The South Sudan government opposes the proposed additional peacekeepers on the grounds that their mandate violates national sovereignty. US ambassador to the UN Samantha Power says she hopes the meeting has "bridged some divides", and insists that peace in the country must go "hand in hand" with justice. IMAGES AND SOUNDBITES
