There was no immediate independent confirmation.

In a statement, the police said Mohammed Abdi Ali, a medical intern at a Kenyan hospital, was in charge of a “terror network… planning large-scale attacks akin to the Westgate Mall attack” in which 67 people were killed in 2013 in Kenya’s capital, Nairobi.

They say he was also “engaged in the active radicalisation” of students and helped recruit Kenyans “to join terror groups in Libya and Syria”.
