There is anger in Egypt's Port Said that supporters of their local football club al-Masry side are being blamed for unrest at the team's stadium which left 74 people dead.
Fans of al-Masry claim Wednesday's deaths were due not to hooliganism but police failings.
There have been claims that security forces targeted visiting al-Ahly fans from Cairo who have been central figures in popular protests, first against deposed president Hosni Mubarak, and now the military.
The official response has been to fire several senior officials and set up an investigation, but in the meantime claims and counter-claims fill the air.
