At least 300 inmates were on the run while one inmate died and three others injured during an attack by unidentified gunmen on a prison in Abuja, Nigeria's capital city, on July 6. The attackers stormed the custodial center in the Kuja area, southwest of Abuja, freeing about 600 inmates, but half the fleeing inmates were re-arrested. It suspected to be carried out by militants of the extremist group Boko Haram. A total of 994 inmates, including convicted Boko Haram conspirators and high-profile public officers standing trial or already convicted, were at the facility before the attack late on Tuesday .
