Nigerian officials have revealed that some 252 inmates are on the run after gunmen ambushed a prison in the central city of Jos.
During a Sunday raid, some nine detainees, one prison staffer and one of the gunmen were murdered, the Correctional Service said via a statement.
So far, about 10 inmates who fled have been rearrested.
The ambushed prison is in the heart of an area housing the state headquarters of the country’s security agencies, including the police.
The attackers who stormed the prison at about 5:20pm on Sunday had engaged the armed squad of the Nigeria Prisons Service (NPS) in a fierce gun battle before breaking into the yard.
Officials said that armed groups, which sometimes try to free their detained members – have frequently aimed at Nigeria’s crowded prisons.
In recent weeks, about 900 inmates were set free after gunmen raided two other facilities.
