I have been informed of the possibility that the trip to Turkey in November may be cancelled. According to my friend in Italy, Turkish authorities are suggesting that it would be too dangerous for the Pope to go visit.
EDIT 9/16: The way things are going and from the comments coming out of Turkey, I think this could very well come about. What would be really courageous is for the Pope to go anyway unless the Turks refuse to allow him entry.
More as it becomes available.
