Terrorist Attack in Athens

The worst terrorist attack in the history of mankind occurs during the opening on the Athens Olympic Games. In what becomes Black Friday - Al Qaida militants strike the Olympic Stadium in Athens packed with over 250,000 people. The first explosions occur when a powerful truck bomb explodes beneath the seats, more than 700 are killed as people try to flee the Stadium in sheer panic. Militants toss grenades into the crowds and vans, parked at each and every entrance packed with over 2000kgs worth of explosives kill hundreds more. Grenade attacks kill many hundreds of other athletes and spectators, as a result, panicked spectators and athletes attempt to flee causing a stampede which makes the Hillsbrough soccer disaster look like a mere school lunch-room crush. Thousands more are killed in this stampede and a hijacked El-Al jet and an American Airlines Boeing 777 smash into the stadium killing those still alive. 
Meanwhile hotels around Athens are blown up and Al Qaida militants storm the Olympic village and hold the entire surviving American Olympic Team hostage before they blow the entire village up, killing thousands of althletes from all around the world. The final death toll was never known in exact figures but the best figure put it at between 55 and 70,000 with one figure quoting 100,000. There were never anymore Olympic Games held after the "Black Friday" events of Athens 2004.
