Interior and Coordination of National Government Dr Fred Matiang'i has said that the recent attacks in Mombasa are linked to the movement of drugs in the county.
In a tweet on Sunday, the tough-talking CS said that a systematic operation had been undertaken and that it would bear fruits.
He said that Kenyans wanted action and no talk.
"There is a clear nexus between the recent Mombasa attacks and the movement of drugs in the region. Kenyans no longer want to hear tough talk — they want results, and we will deliver. We've launched a systematic security operation in the area, and I'm certain it will bear fruits, " the tweet read.
His words come in the wake of attacks in Bamburi, Mombasa said to have been staged by the dreaded Wakali Kwanza gang.
Authorities say that a number of arrests have been made as investigations into the attacks continue apace.
A member of the gang was gunned down after he defied orders to surrender.
Tension descended on the residents of the county as members of the outlawed group as they unleashed terror on innocent people.
Matiang'i has warned members of gangs terrorising Kenyans that they will be dealt with mercilessly.
