The two fatalities in Suez died of gunshot wounds, said the general manager of Suez General Hospital. Earlier, hundreds of protesters attacked the security forces' headquarters in the city with rocks and Molotov cocktails; security forces fired tear gas and warning shots into the air, said Suez Police Maj. Mahmoud Mustapha.
About 25 protesters were injured in Suez, he said.
Thursday's violence occurred as the country began three days of mourning for those who died Wednesday in the Mediterranean city of Port Said. The soccer violence reignited demands for Egypt's military-led government to make reforms and improve security. An emergency parliamentary session was called.
In Port Said, dried blood caked seats in the stadium where fans of the hometown Al-Masry club stormed the field after a 3-1 win over Cairo's Al-Ahly club. Rival fans battled with rocks and chairs, and witnesses said many of the Al-Masry fans carried knives and sticks.
Many suffocated in the crush of bodies that formed as fans attempting to flee the stadium found their escape blocked by a locked steel gate, survivors said.
In the aftermath, horrified fans questioned why police had not stopped the Al-Masry fans from rushing the visitors' stands, why exits were barred and how fans were able to take weapons into the stadium.
"We believe this is something that has been well-organized," said Khaled Mortagy, a member of Al-Ahly's governing board. "I'm sure there are some hidden hands behind this, but we cannot really see, or we cannot really confirm, who is behind all that."
Mortagy said he believes the incident had nothing to do with sports. Members of the club are shaken by what occurred.
At least 47 people were arrested after the clashes, said Gen. Marwan Mustapha, a spokesman for Egypt's Interior Ministry. Mortagy said lawyers for Al-Ahly want to sit in on questioning by prosecutors as an investigation goes forward.
"It's a big catastrophe for Egyptian sports ... a black day for football," he said.
