KHARTOUM, April 15 (Xinhua) -- Sudanese newspapers in Khartoum on Thursday reported that nine members of the ruling National Congress Party (NCP) were killed in south Sudan, but Sudan People' s Liberation Army (SPLA) refuted the report.

"Nine NCP leading members were killed on Tuesday at Tumsah administrative unit in Raja locality of Western Bahral-Ghazal State in south Sudan after altercations with a member of the SPLA, the military arm of Sudan People's Liberation Movement (SPLM)," reported Al Ray Al A'm daily on Thursday.

The paper quoted Chairman of Philip Tola, NCP Bahral-Ghazal sector, as saying that "the killing was committed by a member of the SPLA in the wake of altercations on the polling process."

However, an anonymous military source at the SPLA refuted the incident.

"Such incident has never taken place. It is a fabricated and baseless story," the anonymous source told Xinhua.

"The fabricated killing story comes as part of political harassments and it is an extension of a series of accusations by the ruling party to distort the SPLA and SPLM," he added.

No incidents of violence have been reported during the polling process of Sudan's general elections, which entered its final day Thursday.

However, scattered incidents of violence took place in south Sudan, which is already facing security difficulties due to the tribal conflicts which have claimed the lives of thousands of civilians since the signing of the Comprehensive Peace Agreement ( CPA) in January 2005.
