Clashes erupted in the Egyptian capital tuesday between protesters and police, as the government scrambled to contain mounting anger over post-football match violence that killed 74 people. Black-clad riot police fired tear gas at protesters trying to reach the interior ministry, furious at the lack of police intervention in Wednesday’s violence in the northern city of Port Said. Injured protesters were ferried away by motorbike, with medics saying around 20 people were suffering from tear gas inhalation. Ambulances whizzed through the nearby Tahrir Square, epicentre of last year’s uprising that toppled Hosni Mubarak, towards the site of the clashes. Wednesday’s deadly violence between fans of home team Al-Masry and Cairo’s Al-Ahly marked one of the deadliest incidents in football history and sent shares on the Cairo stock exchange plunging. Hundreds of Al-Ahly fans, wearing their team T-shirts and waving flags, were joined by other team supporters, activists and ordinary Egyptians on the march from their club headquarters towards the interior ministry via Tahrir Square. “This was not a sports accident, this was a military massacre!” the crowds chanted, blaming the ruling military council for the violence. Prime Minister Kamal al-Ganzuri told an emergency session of parliament on the tragedy that the Egyptian football association’s director and board had been sacked, as had Port Said’s security chief. Ganzuri added that the Port Said governor had also resigned, and this had been accepted. However, furious MPs demanded the sacking of Interior Minister Mohammed Ibrahim who sat solemnly in the assembly, listening to accusations of negligence. Wednesday’s clashes erupted at the final whistle of a match which saw home team Al-Masry beat Al-Ahly 3-1. Al-Masry fans invaded the pitch, throwing rocks, bottles and fireworks at Al-Ahly supporters, causing chaos and panic as players and fans fled in all directions, witnesses said. State television ran footage of riot police standing rigidly in rows as pandemonium erupted around them. The interior minister has said most of the deaths were caused by the crush, but medics said some people were stabbed. The health ministry said 74 people were killed, including a policeman. Hundreds were reported wounded, and police said 47 people were arrested. The ruling military announced three days of national mourning. The clashes - blamed by the Muslim Brotherhood on Mubarak supporters - came as Egypt struggles with a wave of incidents related to poor security. Al-Ahly’s most ardent supporters, the Ultras, were active in the revolt that overthrew Mubarak. Politicians, fans and players took to social media to express their fury over the clashes, which cap a year of political upheaval and unrest. “There are dead people lying on the ground! There are dead people in the changing room,” Al-Ahly striker Emad Meteab told the team’s satellite channel. “I won’t play football any more until these people get justice,” a furious Meteab said. World football governing body FIFA yesterday called for a full report on the violence.  “FIFA is in mourning and our thoughts are with the families of all those who lost their lives. Furthermore, FIFA has asked the Egyptian authorities for a full report on the incidents in order to evaluate what happened,” it said a statement.
