The Independent Policing Oversight Authority is condoling with the National Police Service after an attack on a police vehicle on Wednesday.
Authority's Chairperson Anne Makori on Thursday said they are concerned over the matter and highly condemn the act.
This comes after three people were killed in an al Shabaab attack in Garissa on Wednesday morning.
The two police officers and a civilian were in a police vehicle when they were attacked between the Hayley Lapsset Camp and Garissa.
Police and survivors said the attackers first used an improvised explosive device to demobilize the speeding police vehicle before they followed with a rocket-propelled grenade.
They then fired at the vehicle killing the two officers and a civilian as other officers escaped for their safety.
The whereabouts of those who had escaped into a bush are not known.
"It is with shock and dismay that IPOA has learnt of yesterday's heinous attack on a Galmalla police station vehicle resulting in the unfortunate death of an officer and a member of the public in Bura East Sub County, Garissa County," Makori said.
The authority sent condolences to the IG of police Japheth Koome and all members of the National Police Service, families and friends of those who lost their lives in the fatal attack.
IPOA also wished a quick recovery to those who were injured in the attack.
The Authority said that for any country, losing security officers and members of the public through criminal action is a matter of immense concern.
"It is our hope that there will be decisive action by the police leadership proportionate to the gravity of the crime committed yesterday," Makori said.
The Authority noted that over time, it has made various recommendations to the NPS arising from its monitoring operations of various attacks on police officers on duty.
