In Mandera they were hosted by one of the gunmen in the Nairobi's dusitD2 attack last week, and whose cousin Abdirahim Abdullahi, a law graduate from the University of Nairobi, was among those who attacked Garissa University in April 2015, killing more than 147 people, majority of them students.
From Mandera the terrorists moved to Nairobi through Moyale and later joined Ali Salim Gachunge in Ruaka.
