The boy said in tears that some of his schoolmates had been killed by Nigerian aerial attacks.

Katsina is more often ravaged by violent gangs that attack and kidnap residents for ransom.
Boko Haram more often kidnaps school children.
Notorious was the kidnapping of 276 school girls by the terrorist movement in April 2014. Many of them were imprisoned for years and not all girls have yet been found.
