Moroccan envoy's 'sorrow' for Peter Moss death

"Although words can offer no solace, I wish to assure you of my country's firm determination to rapidly bring those accountable to justice."

Mr Moss, a writer and stand-up comedian who lived in West Hampstead and had two children, was one of 16 people who died in the blast, along with a young Jewish couple from Shanghai who had been visiting family in Casablanca for Pesach.

Princess Joumala, who also attended Mr Moss' funeral, said she hoped the victims would rest in peace and that their loved ones would find "the strength and courage to overcome these difficult times."

No group has yet claimed responsibility for the attack, although Moroccan officials said it bore the hallmarks of al-Qaida.
