Four prisoners have been hanged in southern Nigeria, officials say, in what are believed to be the first executions for seven years.
The justice commissioner for the state of Edo, Henry Idahagbon, told reports that the prisoners had been convicted of armed robbery or murder.
Amnesty International said the executions represented “a truly dark day for human rights” in Nigeria.
More than 1,000 prisoners in Nigeria are believed to be on death row.
Local media say President Goodluck Jonathan recently asked state governors to sign death warrants in an effort to reduce crime.
