Six police personnel in north-east Kenya have been killed after assailants attacked a base near the border with Somalia, a regional official said.
No group has claimed responsibility, but Garissa County Commissioner Mohamed Mwabudzo told the BBC the style of the attack followed a pattern of raids by Somali-based Islamist militant group al-Shabab.
He said the officers were ambushed on Sunday at 05:30 local time (02:30 GMT), while they were preparing for their morning prayers.
In addition to the six officers who died, four officers were taken to hospital with injuries.
Al-Shabab frequently mounts cross-border attacks in the area, targeting both the Kenyan military and civilian populations.
Mr Mwabudzo said the "guerrilla-style" nature of the attack aligns with al-Shababs "pattern of cross-border raids aimed at destabilising the region".
"The suspected militia used assorted weapons to overrun the camp," he added.
The camp targeted in the assault was housing reservists - local volunteers who assist the regular police in securing remote areas.
Al-Shabab - affiliated to al-Qaeda - controls large parts of southern and central Somalia.
The group has waged a brutal insurgency against Somalias government for nearly 20 years.
