According to International Christian Concern (ICC), a gang of local Muslims in Elwak, on the Kenya-Somalia border, carried out the sick assault following the deaths of local militant extremists.

The group had been "engaging with police" over the deaths before turning their anger on the non-local Christians, who were in the area for a construction job.

The group of Muslims sought their revenge by stoning to death Fredrick Mukanda Bahati and two other Christian men, who are yet to be named from the September 22 attack.

A witness that asked not to be named told the watchdog: “Fredrick was on top of a new house he was contracted to build. His two assistants were on the ground mixing mortar when the mob arrived in [a] hurry, chanting takbir, takbir, takbir.
