Cairo - Roughly a thousand people rioted in the streets around the Algerian Embassy in Cairo in the early hours of Friday to vent their anger at attacks against Egyptian fans in Sudan the previous night. Angry crowds converged on the embassy, chanting anti-Algerian obscenities, beating drums and burning the Algerian flag, before riot police chased them away from the building with batons.
Young men threw stones and fireworks at the police, who threw the stones back. At one point, fans attacked a police truck, smashing its windows and attempting to turn it over and set it ablaze.
"Where are the newspapers? Where is the television?" they chanted.
In a statement posted to its website, the Egyptian Interior Ministry said 11 policemen and 24 citizens were injured in the melee, and that several cars, including police vehicles, were damaged.
Several main arteries of the exclusive island neighbourhood of Zamalek, where the embassy is located, were taken over by the crowds.
"This is bad. This is Egyptians beating Egyptians," Hussein Abdel- Fatah, 23, told the German Press Agency dpa. "Aren't the police Egyptians too?"
But in some cases, police could be seen walking alongside protesters, and late in the night officers could be seen talking with a group of youths, apparently trying to convince them to go home.
At other points, fans yelled at other fans for throwing rocks at the police, saying the police were also Egyptians.
"The Egyptian people are very angry at what the Algerians did," one protester, who gave his name only as Ahmed, said.
"We stood by them in their war of independence," he said. "We stood by them through the days of terrorism. What other Arab country stood next to Algeria through all this?"
The crowds gathered after altercations in the previous weeks between Algerian and Egyptian fans over a World Cup qualifier and playoff, played in Egypt and Sudan on Saturday and Wednesday nights, respectively.
Much smaller crowds gathered near the Algerian Embassy after Egyptian media reported that Algerian fans attacked Egyptian fans in Sudan following Algeria's 1-0 victory Wednesday night to reach the World Cup next year in South Africa.
Many said they had come out because they had heard "from everywhere," including the websites Facebook and YouTube, that Egyptian fans had been killed in Sudan.
There were no confirmed deaths from football-related violence in Sudan on Wednesday night.
