Factbox-Kidnaps-for-ransom plague schools across northwest Nigeria

(Reuters) – Around 150 students are missing after armed men attacked a school in northwest Nigeria’s Kaduna state, a parent and an administrator told Reuters on Monday.

Armed groups who authorities say are after ransom payments have in recent months targeted schoolchildren across the northwestern part of Africa’s biggest economy and most populous nation.

Islamist groups Boko Haram first carried out such kidnappings in 2014 in the northeast, but armed men, known locally as bandits, have recently adopted similar tactics.

They have taken around 1,000 people from schools since December.

Here are details of other attacks:

* Gunmen kidnapped 94 students and eight staff in a daytime school raid in northwestern Kebbi state on Jun. 17, police, residents and a teacher said.

Three children died while another eight, along with three teachers, were rescued, but the others remain missing.

* One student was killed and at least 10 people were kidnapped in an armed attack on the main campus of the Nuhu Bamalli Polytechnic in Zaria, Kaduna state, late on June 10 according to state authorities.
