Cairo: A court in Egypt yesterday jailed 15 hardcore football fans known as "ultras" for trying to kill the chairman of the popular Cairo-based Zamalek club, an official said.

"Ultras" had already been banned as a group since May 2015 after another court found them guilty of taking part in violence. Since February 2012, the authorities have banned all spectators from football matches in stadiums as games were marred by crowd violence, sometimes deadly.

On Monday, a court sentenced 11 Ultras White Knights, to one year for "planning, participating and attempting to murder Mourtada Mansour", chairman of the club, in August 2014, the official said.
