The threat by the pastor of a fringe Christian church in Florida to burn copies of the Koran on the ninth (anniversary) of the 9/11 attacks has prompted warnings of possible violent protests in other countries from both the international police agency and the US State Department.

It's unclear why the release is taking place now, although there were some suggestion by officials that it was to mark the Muslim holiday of Eid al-Fitr.

The Paris-based think tank's main policy message to governments, however, is don't overdo the austerity.
