About 20,000 people have been killed since the start of the Boko Haram insurgency in Borno State, according to a report from the World Bank that also put the cost of destruction at $5.9 billion.
The report laid bare the extent of the damage since the insurgency began in 2009 and which at one point saw the Islamists control swathes of territory across the northeast.
The report is part of a Post-Insurgency Recovery and Peace-building Assessment, an intervention programme involving the World Bank, European Union and the UN with the six northeastern states.
Assessments in each of the states were carried out in areas including education, health care, water, sanitation, housing, municipal buildings, energy, environment, transport, economy and business.
In Borno, sources conversant with the report told AFP monday that some 20,000 citizens are thought to have been killed during the violence — a higher figure than previous estimates.
In addition, the majority of the more than 2 million internally displaced persons came from the state.
