More than 70 people were killed on Wednesday when riots broke out between soccer fans of rival Egyptian football teams in Port Said, Egypt. An estimated thousand fans were injured in the riots, but authorities remain uncertain of exactly how many fans were killed.

Al Jazeera reported that supporters of the victorious al-Masry team ran on to the field following a game with the country's top club al-Ahly. Al-Masry enjoyed a rare 3-1 win and, in response, fans allegedly stormed the field, chasing players and attacking supporters of the opposing team by throwing rocks, fireworks and bottles at them.

This is not football. This is a war and people are dying in front of us. There is no movement and no security and no ambulances, Abo Treika told the Ahli television channel. I call for the premier league to be cancelled. This is horrible situation and today can never be forgotten.

The two teams have a long history of conflict with clashes frequently erupting between their fans, Al Jazeera reported. The Telegraph claims that there has been increased violence at soccer matches in North African in the past year, potentially related to the political unrest that has swept the area.

Unfortunately, the deadly soccer clash in Egypt is not the first of its kind. There have been a number of deadly football-related riots leading to hundreds of deaths and thousands of injuries. Take a look at the deadliest incidents in football history.
