CAIRO—Scores of Egyptian soccer fans were crushed to death while others were fatally stabbed or suffocated after being trapped in a long narrow corridor trying to flee rival fans armed with knives, clubs and stones, in the country's worst ever soccer violence that killed at least 74 people, witnesses and health officials said Thursday.
If it's not football fanatics, then it's religious fanatics. But in all of this we must not forget that Egypt is a very poor country:
"The average individual annual income in Egypt is US$2,077," said the report focusing on 2009-2010, but noted that the number of poor people is on the rise. Some 12.2 million Egyptians, it said, lived in over 1,200 slums; 3,728 villages did not have access to sanitation; and 17 million adults were illiterate.
