Two leading members of the Communist Party of Sudan (CPoS) were detained in Khartoum yesterday after their return from Juba, the capital of South Sudan, earlier that day. They had visited South Kordofan to talk to Abdelaziz El Hilu, leader of the Sudan People’s Liberation Movement-North (SPLM-N), and Abdelwahid El Nur, leader of the Sudan Liberation Movement in Darfur.
