Another good account of the sectarian tensions in Upper Egypt, and their interplay with national politics. 

It all started when a group of Christians in the village built a speed bump near their home to decrease car accidents. When a Muslim man hit it, not knowing it was there, he started swearing at them and insulting their mothers and fathers. On August 10, a Muslim man known to be radical came in person to threaten the village church. The following day, as Christians went to Sunday mass, Muslims were already sending calls via mosques to attack them, Nasrallah recounts.
