The suspected Al Shabaab militants attacked a Mandera bound bus between Kotulo and Wargadud in Tarbaj, Wajir county.
They reportedly flagged down the bus, ordered the passengers out before ordering non-locals out of the bus.
Shabaab militants then held non-locals captive and released the bus to proceed with the journey as they began shooting them.
According to police reports, six police officers attached to Anti-Stock Theft Unit who were returning to their work stations and a doctor were among the non-locals killed.
Northeastern regional commissioner Mohamed Birik said special forces have already been deployed in the region to conduct operations as they pursue the militants who are reported to have escaped back Somalia.
Wajir Governor Mohamed Abdi condemned the attack and urged the national government to heighten surveillance in the area and to be pro-active not to wait until such incidences occur.
