Emerging details indicate that as earlier stated by the Inspector General of Police Joseph Boinnet, the Tuesday terror attack on Nairobi's DusitD2 complex was well planned.

The strategy heavily relied on the suicide bomber who blew himself near the Secret Garden Restaurant.

His role was to cause havoc, terror and confusion at the scene.

The suicide bomber, dressed in a suicide vest, was to kill as many people as possible at the restaurant before signaling the other group of terrorists to come in.

According to the Standard, the remaining group would emerge from the entrance and open fire on the confused and fleeing people who would most likely be going for the entrance.

This way, the group of four would kill as many as possible, a plan that was however thwarted when the gunmen delayed appearing as per the plan.

According to a man who happened to pass near the suicide bomber seconds before he went up in the explosion, he was complaining to someone on the phone that the group was nowhere to be seen.

It is reported that he was speaking to Ali Salim Gichunge, the team leader who was, however, leading from outside, reportedly his rented home in Muchatha, Ruaka in Kiambu.

However, despite the foiled plan, the group still went ahead to kill 21 people before it was neutralized by officers from the elite Recce squad on Wednesday dawn.
