A policeman and his wife were killed in a frenzied knife attack at their home in a Paris suburb on Monday night by a man who reportedly shouted “Allahu Akhbar”.

The man had been sentenced in 2013 for taking part in a jihadist organisation with links to Pakistan, press agency AFP reported on Tuesday.

They identified him as Larossi Abballa, 25, adding that he had been sentenced to a three-year term - six months of which were suspended - for "criminal association with the aim of preparing terrorist acts," in a trial with seven other defendants.
