Five security officers were killed on Tuesday in an attack by suspected Al-Shabaab terrorists on the Elwak-Kotulo road in Mandera.
The attackers also burnt a police lorry while several officers were injured in the evening ambush.
Mandera South deputy county commissioner Daniel Bundotich said three police reservists and two Administration Police officers died in the attack.
“We lost five security officers in the attack while on patrol on Elwak-Kotulo road,” he said.
A second contingent of GSU personnel that was responding to the first attack was also ambushed, Mr Bundotich added.
