2 Kenyan military officers died after an Armoured Personnel Carrier they were in was hit by a roadside explosive in Damasa, Mandera County.
Three others were injured in the explosion that badly damaged the APC.
Security personnel in the area said the Improvised Explosive Device had been set up by Al-Shabaab militants.
The injured were evacuated in a military chopper that landed the area minutes later.
North Eastern regional coordinator Mohamud Saleh said he had not received full details of the incident.
“There was also an exchange of fire between the militants and the survivors before the terrorists escaped,” added Saleh.
In June this year, 7 police officers died after another armoured personnel carrier (APC) was blown up by suspected Al Shabaab terrorists.
One civilian also died in the explosion.
The disintegration of the APC after hitting an improvised explosive device planted on the road sent shock waves in the security sector as questions emerged over the reliability of the vehicles recently purchased from China.
The officers were headed to Mokowe, from a rural border patrol unit in Mangai for refuelling when the APC ran over the bomb.
