KHARTOUM (Reuters) - Sudanese rebels shelled the capital of the country's main oil state on Tuesday, witnesses and the insurgents said, in what the insurgents said was retaliation for government air strikes.
Sudan's armed forces spokesman did not respond to phone calls seeking comment, but Sudanese television reported five civilians were killed in the shelling.
Fighting has raged across Sudan's South Kordofan state since June last year, when rebels and government forces started clashing shortly before South Sudan declared independence.
The violence in South Kordofan and nearby Blue Nile state, which both border South Sudan, has forced hundreds of thousands of people to flee their homes, and aid agencies have warned of a humanitarian crisis in the region as food supplies run low.
The rebel Sudan People's Liberation Army North (SPLA-N) started attacking Kadugli on Tuesday afternoon, the group's spokesman Arnu Lodi said.
The shelling was an act of "self defense, especially after the continuing air strikes by government forces on SPLA-N positions and on civilians," he told Reuters
Lodi said the rebels had targeted only military sites and that they had warned civilians to stay away from those areas.
Witnesses conformed several shells landed in Kadugli on Tuesday.
South Sudan split away from Sudan in July last year under a 2005 peace deal that ended decades of civil war.
The SPLA-N rebels had fought alongside the southern insurgents during that conflict, but partition left them in Sudanese territory.
The insurgents now say they are fighting to protect their ethnic minorities from oppression, while Khartoum accuses them of trying to spread chaos at South Sudan's behest.
South Sudan denies supporting the SPLA-N, but the charges have nevertheless complicated talks between Juba and Khartoum over unresolved issues left from partition.
