Egypt has seen a resurgence of unrest after last week's deadly attack on football fans loyal to the revolutionary movement. One eyewitness reports being amazed at how few police were at the match in Port Said. The military has denied it orchestrated the violence -- but it stands to gain from the chaos.

Mohab Raid, 18, a fan of Cairo football club al-Ahly, wasn't surprised by the abuse and the bottles hurled at him and his friends outside the train station of Port Said last Wednesday. That was part of the standard ritual whenever his team played an away game. The fans of the opposing club, first-division Port Said, wanted to fight the visiting supporters. "A pure sporting matter," says Raid.

But something was different this time. He noticed it when he entered the stadium at 4 p.m. "There were far fewer police than usual. I seriously asked myself how they were supposed to protect us," he says.

Raid doesn't scare easily, he's a member of a tight-knit community of football fans known as "ultras." Every big Egyptian football club has ultras, they like to fight and know how to throw a punch. But the al-Ahly ultras are much more than that -- they're heroes. When the camel riders and thugs of the old Mubarak regime tried to chase demonstrators out of Tahrir Square a year ago, they fought back. Since then they have been seen as the protectors of the revolution.

Raid says the al-Masry ultras are largely apolitical. That is why he didn't expect to see people trampled to death, or stabbed and beaten in front of his eyes. At around 7 p.m., shortly after the final whistle, thousands of people suddenly ran onto the pitch. Raid says the stewards had opened the gates and withdrawn.

"The people who ran towards us weren't fans with football shirts on, they were people from outside wearing dirty everyday clothes. They climbed up the stands and chased us with knives, swords, clubs and iron bars. While the al-Ahly players and some of their fans managed to flee into the changing rooms, others were pushed against the wall and thrown to the ground. The gates at the back were kept shut and the stadium became a death trap.
