The five defendants, who are subject to an international arrest warrant issued by Morocco, include a Briton of Moroccan origin and two men from Arab countries, legal sources said on Friday.

Their names and countries of origin have not been revealed. The Moroccan-born British man is Mohamed Guerbouz who lives in London. 

They were sentenced in absentia under the country's anti-terrorism laws for "setting up a criminal association with the aim of preparing and committing terrorist acts, fundraising for terrorist operations and forgery and use of forgeries." 

Moroccan press reports said one of the five, Moroccan Karim
Mejjati, was allegedly involved in setting up "terrorist cells in
Morocco and Saudi Arabia". 

Forty-five people died in the suicide attacks in Casablanca on
16 May.
