ABUJA, Nigeria (AP) — Nearly 300 kidnapped Nigerian schoolchildren were released Sunday, local officials said Sunday, more than two weeks after the children were seized from their school in the northwestern state of Kaduna.

Kaduna state Gov. Uba Sani did not give details of the release of the 287 students, who abducted from their school in the remote town of Kuriga on March 7. In a statement, he thanked Nigerian President Bola Tinubu “particularly ensuring that the abducted Kuriga school children are released unharmed.”

Tinubu had vowed to rescue the children “without paying a dime” as ransom.

Abductions of students from schools in northern Nigeria are common and have been a major source of concern since 2014, when Islamic extremists kidnapped over 200 schoolgirls in Borno state’s Chibok village. In recent years, abductions have been concentrated in the country's northwestern and central regions, where dozens of armed groups often target villagers and travelers for ransom.
