Federal government has resumed cash payments for former militants in the oil-rich Niger Delta, an official said. The payments were agreed under a 2009 amnesty meant to end a wave of militant attacks on oil and gas facilities.
However, Nigeria stopped the payments in February.
An emailed statement quoted by the Bloomberg news agency says that President Muhammadu Buhari told the former fighters that he appreciated their patience.
Each ex-militant is entitled to $200 (£150) a month plus job training.
This comes as the government is dealing with a new wave of militant activity which has damaged the country's oil sector.
