Violence has flared once again in the capital of Sudan's Blue Nile border state, raising concerns over the continuing lack of humanitarian access there , BBC reported.
Thousands of people have already fled their homes because of ongoing tensions between government soldiers and forces linked to South Sudan's ruling Sudan People's Liberation Movement (SPLM).
Blue Nile State occupies a strategic location as it borders South Sudan and Ethiopia. The state is also neighboring Sudan's South Kordofan State where similar clashes are taking place between the SPLA and the government troops.
The SPLA's northern faction, which fought alongside the SPLA in the civil war between north and south Sudan, has around 20,000 fighters in Blue Nile State.
