The Somalia-based al-Qaeda-linked group al-Shabaab has “ordered” Christians to leave three counties in northeastern Kenya to allow local Muslims to get all local jobs, according to the U.S.-based persecution watchdog International Christian Concern.

“Muslim teachers, doctors, engineers, and young graduates from the northeastern province are unemployed. Isn’t it better to give them a chance? There is no need for the presence of disbelievers,” al-Shabaab’s spokesman, Sheikh Ali Dhere, said in an audio clip posted online, referring to the counties of Garissa, Wajir and Mandera.

In the 20-minute clip, the spokesman urged Somali-Kenyans to drive all non-Muslims out if they do not leave on their own.

The majority of the people living in the three counties are Somalis, who fled to Kenya due to war and violence in Somalia.
