7 February 2011 - The UN Secretary-General's panel monitoring Sudan's referenda welcomed today's official announcement on final results of Southern Sudan's referendum, which showed that an overwhelming majority of voters had opted for secession.
Closure of UNMIS
UNMIS wound up its operations on 9 July 2011 with the completion of the interim period agreed on by the Government of Sudan and Sudan People’s Liberation Movement in the Comprehensive Peace Agreement (CPA), signed on 9 January 2005.
The mission ended its six years of mandated operations the same day South Sudan declared independence, following a CPA-provided referendum on 9 January 2011 that voted overwhelmingly in favour of secession.
In support of the new nation, the Security Council established a successor mission to UNMIS – the UN Mission in South Sudan (UNMISS) – on 9 July for an initial period of one year, with the intention to renew for further periods as required.
