Several buildings in a police officers' club complex in the Egyptian capital were in flames on Saturday, an AFP reporter said.
According to a senior security official, hardcore football fans known as the Ultras stormed the complex and set fire to the buildings.
Residents of the affluent island where the club is situated were using garden hoses to try to extinguish the flames. Other buildings in the complex had their windows smashed.
Several hundred members of the Ultras were also making their way towards the interior ministry, state television reported.
