Motive unclear in France beheading attack

Even as French investigators piece together a clearer picture of events that led on Friday to the beheading of a transport firm manager and attempted destruction of a chemicals plant, the real motivation of the chief suspect remains elusive.

Yassin Salhi, the 35-year-old delivery man who killed his boss, was a father of three with a permanent job and an apartment in a Lyon suburb, and a clean criminal record.

He has denied any religious motivation, despite an attack which bore the hallmarks of a jihadist act.
