The Turks are complaining about Benedict's quoting a comment made by the Byzantine Emperor Emperor Manual II Paleologos. The quote: "Show me just what Muhammad brought that was new and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached."
Now the Turks are asking for an apology, etc. The other references to Muslim outrage are from a Pakistani cleric and a mention of Kashmiri police seizing newspapers carrying coverage of the Pope's words. That was a bid to prevent tension in the far corner of India.
The inferiority complex of institutional Islam once again shows itself. Let us all pray that the teenagers of Turkey don't take this slight as personally as they did the cartoons and start attacking priests.
