Casablanca/Rabat, Morocco  - Five years after Morocco's deadliest suicide bombings killed 45 people in Casablanca, the north African kingdom remains engaged in a relentless chase for Islamist terrorists.

Thousands of people have been detained, including dozens who have been abducted illegally by the secret service and taken to detention centres such as the ill-famed Temara near the capital Rabat, according to human rights groups.
