Nairobi - A Kenyan official says five police officers have been killed in a suspected extremist attack in the country's northern Mandera County.
Regional Co-ordinator Mohamud Saleh said on Friday the attackers targeted government administration offices and Kenya police camps.
He said the militants blew up a telecommunications mast to cut off cell phone contact before the attack.
The Somalia-based al-Shabaab extremists have vowed retribution against Kenya for sending troops in 2011 to fight the extremists in the Horn of Africa nation. Kenyan security has managed to restrict a wave of al Shabaab attacks to border areas with Somalia in recent years.
Police said they prevented a major attack by the militants in Nairobi last week. Security agents have been accused of serious human rights violations rights while carrying out their operations.
