At least 700 students have been abducted in Northern states since December.
And that figure is changing every day with reports of more attacks and abductions.
Dozens of students managed to escape a raid on Monday, while their three teachers were taken.
It happened in the northwestern Kaduna state and it's the first such attack on a primary school.
Armed gangs locally known as bandits are suspected.
They usually seek lucrative ransom to release the victims.
So, how challenging are they to President Muhammadu Buhari?
