Police in Morocco have arrested three people in connection with a bombing in Marrakesh that killed 16 people.
Fourteen of those who died in the attack on 28 April at a cafe popular with holiday-makers were foreigners, the BBC reports.
Police say the chief suspect was loyal to al Qaeda.
The official Moroccan news agency reports that the three detained are all Moroccans.
The attack was the deadliest since a suicide bombing in Casablanca in May 2003 in which 45 people were killed.
