Riot over Egypt football defeat
Egypt-Algeria World Cup anger turns violent in Cairo
Riot police in the Egyptian capital, Cairo, quelled a violent demonstration near the Algerian embassy in the early hours of Friday.
Egyptian protesters reportedly hurled firebombs at police protecting the embassy and overturned a police van.
Egypt's Interior Ministry said 35 people were injured.
The clashes stem from Egypt's defeat by Algeria in a World Cup qualifying match on Wednesday, securing Algeria the last African place for next year's finals.
On Friday Alaa Mubarak, the son of Egypt's president Hosni Mubarak, made a rare public statement calling for a "tough stance" to be taken against Algeria.
