At least seven passengers were killed on Monday morning after a matatu they were traveling in ran over an Improvised Explosive Device (IED) along the Arabia-Mandera highway.
The incident comes in the wake of several terror alerts issued by foreign governments last week warning of imminent terror attacks in Kenya.
AlShabaab militants have increased attacks on civilians in Tana Delta, Lamu & Mandera in recent months.
Last week on Wednesday, Suspected AlShabaab militants sprayed a vehicle ferrying court officials with bullets at Lango la Simba on Lamu-Witu-Garsen road. The victims survived the attack but were left nursing bullet wounds. The incident was confirmed by Coast Regional Commissioner John Elungata.
A few days prior to the attack, 8 construction vehicles that are part of the LAPSSET road project were set ablaze in a suspected AlShabaab attack. The vehicles belong to the China Communications Construction Company.
The LAPSSET road project is expected to help control the rampant attacks in North Eastern, where the militants plant IEDs on the current rough terrain.
Security has been intensified in the country following the terror alerts issued by the French and UK embassies in Kenya.
