At least 22 soccer fans were killed and 35 injured when police and supporters of Zamalek team clashed at a football (soccer) game in Cairo, local media report.
The Association of Zamalek Supporters, known as Ultras White Knights, published a list of the victims' names.
Earlier, authorities said 14 were killed, and the death toll is expected to rise.
The clash happened at a match between two Cairo clubs, Zamalek and Enppi. Police used teargas to disperse the crowd, security forces said.
"Huge numbers of Zamalek club fans came to Air Defense Stadium to attend the match ... and tried to storm the stadium gates by force, which prompted the troops to prevent them from continuing the assault,'' the Interior Ministry said in a statement, without giving more details.
The deadliest riot in Egypt soccer history came during a 2012 match when Port Said's Al-Masry team hosted Cairo's Al-Ahly. That riot killed 74 people. Later that year, angry fans burned down the headquarters of Egypt's Football Association, protesting its decision to resume matches before bringing those behind that 2012 riot to justice.
Egypt has curbed the number of people allowed into soccer matches since that riot, prompting fans to often try to storm soccer grounds that they are banned from entering.
