The uproar over a Florida pastor’s threat to burn the Koran is not going away. Sixty people were injured in Kabul, Afghanistan during a rally against the idea Wednesday. The crowd in the western part of the city shot at police and threw stones –35 of those injured were police. The Koran has been at the heart of a number of violent struggles in Europe, Central Asia and the middle east in recent days. The concern is not just for locations outside of the U.S.. Authorities here are on alert for violence that may grow out of similar protests.
