The incident happened at about 4 pm and spread late into the evening hours, police said adding operations on the road were paralyzed.
The bandits shot indiscriminately at the officers leaving the officers with serious multiple injuries. Three died in the hospital.

Three people had earlier been killed in the same area and one was critically injured by gunmen who attacked a matatu at Kakong area of Turkana South.

The highway attack is the fourth one this month alone, the Matatu operators said as they demanded enhanced security on the route.
