The Nigerian army on Sunday rescued students and staff who were abducted by gunmen from a school in the country’s north earlier this month, the military said, days before the deadline for a ransom payment.

School officials and residents had said 287 students were taken on March 7 in the town of Kuriga in the northwestern state of Kaduna. A military spokesperson said 137 hostages – 76 of them female and 61 male – were rescued in the early hours of Sunday in neighbouring state of Zamfara.

“In the early hours of 24 March 2024, the military working with local authorities and government agencies across the country in a coordinated search and rescue operation rescued the hostages,” Major General Edward Buba said in a statement.

A security source said the students had been freed in a forest and were being escorted to Kaduna’s capital for medical tests before being reunited with their families.

Kaduna Governor Uba Sani earlier put the number of kidnapped at over 200. Given the discrepancies in numbers reported, it was unclear if any hostages remained captured. Some Kuriga elders said Sani had told them all hostages had been freed.

Jibrin Aminu, a spokesperson for the Kuriga parents, said he would clarify numbers on Monday when families had been given the chance to “take account of their kidnapped children.”00:18Senegal’s opposition take early lead in election poll

The rescue took place just days before a deadline to pay a 1 billion naira ($690,000) ransom for their release.

Abductions at Nigerian schools were first carried out by jihadist group Boko Haram, which seized 276 students from a girls’ school in Chibok in northeastern Borno State a decade ago. Some of the girls have never been released.

But since then the tactic has been adopted by criminal gangs without ideological affiliation.

Kidnappings by criminal gangs demanding ransoms have become an almost daily occurrence, especially in northern Nigeria, tearing apart families and communities that must pool savings to pay ransoms, often forcing them to sell land, cattle and grain to secure the release of their loved ones.
