Sudanese rebels say they have launched a major operation against an area in South Kordofan which a controversial counter-insurgency unit showed off to journalists after "liberating" it last week. "Our forces launched (a) big offensive in Daldako", Arnu Ngutulu Lodi, spokesman for the Sudan People's Liberation Movement-**rth (SPLM-N), told AFP late Saturday in an email. Troops from Rapid Support-2 said they had seized the strategic Daldako area, 17 kilometres (11 miles) **rtheast of South Kordofan's state capital Kadugli, on May 18. But on Sunday the Al-Sudani newspaper, quoting Defence Minister Abdelrahim Mohammed Hussein, said the Daldako field commander of Rapid Support-2 had been killed in the rebel counter-attack.
