Fakhry Tardos holds a portrait of his son, who was killed in the attack, as tears roll down his face. "The whole floor was covered in blood," he says of the morgue that was flooded with bodies following the attack. Head in hands he weeps bitterly. "There is no joy in our festival this year," says Besoi Meghdi a survivor of the attack. He watched as one friend bled to death. The attack was a shock but Coptic priest Emdy Amzy saw the tension building. The number of attacks on Copts has been increasing in recent years and he blames hate-preachers and the government for not standing up to the radicals. Yet it is not only Muslims now who have become more polarised. "I spoke with a very reputable man who said that Christians may have weapons". The pain and the shock is only amplified by the close traditional links between the Copts and Muslims. Fakhry Tardos may have lost his only son but he says he refuses to hate his neighbours. He and his Muslim neighbours now mourn the dead but more attacks will surely put greater strain on this fragile relationship.
