THE troubled southern Nigerian oil town of Warri has been declared an official “disaster zone” by the governor of Delta State, James Ibori, an aide said on Monday. Ibori over the weekend declared the town a disaster zone to allow the state to provide relief for people made homeless by inter-communal fighting which had devastated the centre of the city last week. Ibori also promised to set up an urban authority to develop the town. The Warri region has in the past two weeks been hit by a flareup in inter-communal fighting with up to 200 people killed and around 100 homes destroyed. President Olusegun Obasanjo visited the town on Friday and promised to set up a development authority for the entire Niger delta region.
