Aerial attack in South Sudan kills five

(CNN) -- Five people were killed and five others wounded after an airplane dropped bombs Saturday on a town in South Sudan, a military spokesman in that fledgling country said -- though a Sudanese military spokesman denied any such attack.

Col. Philip Aguer, a spokesman for the Sudan People's Liberation Army of South Sudan, said that the aerial strike hit a market area in Rubkona, which is part of Unity state, at 1 p.m. Saturday (6 a.m. ET).

Abiemnom County in that state, as well as two counties in Warrap state, were also attacked Saturday, Aguer said.

But Al-Sawarmi Khalid, a spokesman for the Sudanese Armed Forces, said, "We have not carried out attacks into South Sudan."

Both military spokesmen referenced Heglig, a key oil installation in South Kordofan state that produces nearly half of Sudan's oil and was seized by South Sudan's military this week. Read More
