"The most important thing now is to get all the remaining children released," he said."I'm so happy what God had done for us, it is our day," said mother Jumai Francis.
Of the five children who escaped on July 21, two were found by police and the other three made their own way back to the school, Hayab said.After the kidnapping, the gang asked the school for food and a ransom to free the hostages. Boko Haram fighters first kidnapped children from schools in 2014, when they took more than 200 girls from their dormitory in Chibok, causing a worldwide public outcry.
Many though remain captive, including a hundred children abducted in early June from a Muslim school in the neighbouring state of Niger, and still held hostage.
