More than a week after an outbreak of ethnic violence in the oil-rich Delta region of Nigeria, the army sent by the government to quell the disturbances claims to have tightened its control on the volatile conflict zone. At the heart of the conflict are youths in the Niger Delta from the local Ijaw community, which claims to be the majority ethnic group in the area. They complain that they have been marginalised by central government and receive virtually none of the benefits from the oil wealth, which they say comes from their traditional lands in the region.
