The murder of three teachers by suspected Al Shabaab militants in Wajir County has yet again confirmed the delicate situation in northern Kenya. The brazen attack in Qarsa Primary School on Friday morning, which left scores injured, aggravated security fears in much of Mandera, Wajir and Garissa counties. For about 10 years now, the Islamic insurgents have held a risky, if sporadic, sway in the north, the result of which has been mass murders, destruction of property, and kidnapping of security personnel and tourists.
The militants, unhappy with the presence of Kenyan troops in Somalia, have been determined to prove a point. In November 2014, they intercepted a bus and killed 28 passengers in Mandera. A month later, they ambushed a quarry and shot 36 people.
