Nigerian pupils taken by gunmen in a mass abduction in the north-western town of Kuriga earlier this month have been freed “unharmed”, officials say.
Kaduna state governor Uba Sani said they had been rescued thanks to the courage of the security forces.
The school authorities had said more than 280 children were taken, but the army said 137 hostages had been freed.
It said the operation took place in the early hours of Sunday morning, days before a ransom deadline.
Officials have not yet commented on the discrepancy in numbers
In previous cases, hostages have been able to flee from their captors as they trek for days to forest hideouts.
A top government official, who asked not to be named, has told Hausa that one of the teachers taken from Kuriga died in captivity. The group was held for 17 days in total.
Kidnap gangs, known as bandits, have seized thousands of people in recent years, especially in the north-west.
Six mass abductions this month have rocked parts of northern Nigeria, despite an overall fall in the number of such attacks over the past year.
Those kidnapped are usually freed after a ransom is paid.
