Two of the 14 men who carried out last week's suicide bombings in Casablanca are alive and in custody.
The Interior Minister Mustapha Sahel had previously announced that one bomber was allive.
The inquiry into the attack that claimed 41 lives, including those of 13 bombers, had quickly focused on the banned Assirat al Moustaqim (The Straight Path), now feared linked to Osama bin Laden's al-Qaeda network.
Justice Minister Mohamed Bouzoubaa revealed that some of the bombers had recently returned home from abroad and were linked to Assirat al Moustaqim.
Since Friday, police have made dozens of arrests in places frequented by Casablanca Islamists, complementing an investigation that has been under way for several months.
About 40 people accused of belonging to Assirat al Moustaqim and another banned organisation, the Salafia Jihadia, had already been arrested.
