Gunmen stormed a jail in south central Nigeria late on Sunday, blowing up the perimeter fence and freeing almost all the inmates, authorities said.
An officer and a soldier were killed in the attack, and two guards went missing, according to the interior ministry. This was the second major jailbreak in Nigeria this year.
In a gun battle with guards, the attackers destroyed the fence on three sides of the medium-security prison at Kabba in Kogi State, southwest of Abuja, authorities said.
The interior ministry said 28 of the 294 inmates at Kabba had not escaped, meaning 266 had. Initially, the prison service had estimated 240 fugitives.
At the time of the raid, 15 soldiers, 10 police officers, and 10 armed prison guards were on duty at the Kabba jail.
