In a statement, a special adviser to the president confirmed that all the girls taken from the school in Kebbi State had been accounted for, noting that the incident triggered copycat kidnappings in two other Nigerian states.
Tinubu said that more personnel would be deployed to “vulnerable areas to avert further incidents of kidnapping”.
In a separate post on X, Tinubu wrote: “The Air Force is to maintain continuous surveillance over the most remote areas, synchronising operations with ground units to effectively identify, isolate, disrupt, and neutralise all hostile elements.”
More than 1,500 children have been abducted from Nigerian schools since 2014, when 276 girls were abducted during the infamous Chibok mass abduction.
On Friday, at least 300 children and staff were abducted from St Mary’s School, a Catholic boarding school, in Nigeria’s Niger state.
Fifty of those abducted from the school have since escaped, according to the Christian Association of Nigeria – but at least 250 remain unaccounted for.
The main Catholic cleric in the region has told the BBC that Nigeria’s government is making “no meaningful effort” to rescue those still missing.
The abduction at the school was the third to hit Nigeria in a week, forcing President Bola Tinubu to cancel his trip to the G20 summit, held in South Africa at the weekend, to deal with the crisis.
UN education envoy Gordon Brown called on the international community to “do our utmost” to support efforts to return the abducted children.
Brown, a former UK prime minister, said: “It’s also incumbent on us to ensure that Nigerian schools are safe spaces for learning, not spaces where children can be plucked from their classroom for criminal profit.”
