AINA:

Clashes between Muslims and Christian Copts recently spurred Egyptian security forces to impose curfews on two towns in the governorates of Bani Swaif and Dakahlia.
In Kafr El Barbari in Dakahlia, mayhem broke out Tuesday after 18-year-old Mohamed Ramadan Ezzat, a Muslim, was apparently stabbed to death by John Emile Gerges, a Christian grocer, in a dispute over the price of a carbonated drink. (the Muslim was opposed to pay all that to a filthy Christian pig, wasn't he?).
After Ezzat's burial later that same day, 25 people were injured as hundreds of angry Muslims attacked Gerges' and other Coptic residents' houses, throwing stones and trying to set the homes on fire. The violence spurred many to flee the town, which is inhabited by about 1,000 Copts and 3,000 Muslims.
Most Copts are staying at home in fear of other possible attacks. After the incident, dozens of security vehicles, firefighters and ambulance personnel formed a security barrier around the town as police forces tried to prevent anyone from entering or leaving the village. Security forces attempted to intervene to bring peace between the town's Muslim and Coptic leaders, and financially compensating Ezzat's family was being suggested as a possible resolution to end the conflict.
Meanwhile, six people were injured and 15 others were detained by police in the wake of similar confrontations between Muslims and Copts in the Bani Swaif village of Ezbet Gerges on Friday.

Another case of intra-religious violence in "moderate" Egypt. What about some "dialogue" from the Alliance of Civilizations?

DISCLAIMER: I don't like what the Christian guy did (stabbing someone to death, although there is not much to judge on the case: self defense? abusive prices?...). But why on earth all the community has to pay because one of them stabbed other guy?.
