Al-Qaida is thought to have been behind the bomb in Morocco that left a former JC writer, a Jewish couple from Shanghai, and 13 others dead.
Morocco's Interior Minister said Thursday’s bomb, believed to have been exploded remotely, reminded "of the style used generally by al-Qaeda."
A video featuring a threat to Morocco posted before the blast has also been attributed to the group al-Qaeda in the Islamic Maghreb (AQIM).
Mr Moss, a father-of-two from north London, was following in the footsteps of many visitors to Morocco by eating at the Argana cafe in Marrakesh’s historic Djemma El Fna Square.
