At least 25 are dead after a riot broke out outside a soccer game in Egypt. Authorities said there was a stampede and police and fans started fighting, according to Fox News.

Before a match between Egyptian Premier League clubs Zamalek and ENPPI at Air Defense Stadium east of Cairo, protests started, much like the riots that killed 74 people three years ago, according to Fox News.

There is animosity between the public and police after a female protester was shot in Cairo and other protesters were arrested. President Abdel-Fattah el-Sissi vowed to stop Islamic militant violence and create a more stable Egypt, but a violation of human rights would be expected, like outlawing demonstrations and protests.

Per the Cabinet, all upcoming soccer matches in Egypt have been postponed until further notice, according to Fox News.

There are a few versions of what sparked the violence, according to Fox News. Security claims Zamalek fans tried to enter without tickets. Only 10,000 fans were permitted inside the stadium, which has a capacity of 30,000, according to the Interior Ministry.

Zamalek fans claim only a tiny barbed wire door had been opened to let all the fans in, so shoving ensued. The fans, also called "White Knights," said police responded with tear gas and birdshot.

It isn't uncommon for Ultras, Egypt's hardcore soccer fans, to come head-to-head with police. The group is said to be very political and many of Ultras' members took part in the 2011 coup de étàt against President Hosni Mubarak, according to Fox News. They are often considered one of the most organized activist groups in Egypt - second only to the Islamist Muslim Brotherhood, a terrorist organization.
