In theory, this is supposed to be something different from the previous warnings from the US. BBC News:
Saudi Arabia has warned France it is the target of an imminent al-Qaeda attack, French Interior Minister Brice Hortefeux has said.
He said Saudi intelligence agencies spoke of a threat to Europe, and "France in particular", from al-Qaeda in the Arabian Peninsula.
France is already on high alert following warnings of possible attacks aimed at France, Germany and the UK.
