At least four people were Wednesday killed when a vehicle they were traveling in ran over an Improvised Explosive Device (IED) along the Garissa- Bura road.
The explosion destroyed the four-wheel drive vehicle belonging to the Kenya National Highway Authority (KeNHA) engineers killing the four occupants, police said.
Police who attended the scene said they recovered three bodies while a fourth one was badly destroyed in the impact.
A spokesman for KeNHA said the deceased were workers of a contractor working on the road.
Police blamed the attack on al-Shabaab militants operating in the area.
The engineers were in three vehicles and were on routine assessment of the LAPSSET Road when they were attacked by suspected al-Shabaab elements who had placed an IED on the old LAPSSET road which exploded destroying the first vehicle.
The other vehicles turned back to Hailey camp which is under police protection.
The team was traveling from Garissa to Hailey Chinese Camp and then to Bura East when the incident happened, police said.
North Eastern regional police boss George Seda said the attackers escaped from the scene and efforts to trace them were ongoing.
