The SPLM-N accused the Sudan government of refusing to agree on the inclusive process to resolve the conflict in the whole country.
SPLM-North delegation spokesperson Mubarak Abdurrahman Ardol on Saturday blamed Khartoum of violating the UN Security Council Resolution 2046 to resettle peace in the affected areas, Voice of Peace reported.
He claimed that Khartoum postponed the discussion to allow humanitarian aid in South Kordofan and Blue Nile states.
AU cancelled the negotiations between the Khartoum and SPLM-N without indicating the time to resume another round of peace talks.
