A Frenchman described as "radicalised" has been arrested in Morocco after flying there on a Ryanair flight with knives and a gas bottle in the hold, a local government official said.

The 31-year-old man, who had been under house arrest in France, was held upon his arrival in Fez.

Authorities discovered the items in his luggage, which also included a black balaclava.

In a statement, Ryanair said: "This is a matter for the security authorities at Nantes Airport who are investigating this issue."
