At least 23 people are now dead—after violence erupted between rival families in Egypt's city of Aswan. It all started when students—belonging to the families—scrawled insulting graffiti on the walls of a local school. The Interior Ministry said the two sides used guns and petrol bombs. Several homes were burned to the ground before police were able to stop the clashes on this street. Security sources said reinforcements from the army were requested to prevent more bloodshed.
