The head of the Algerian football federation has blamed his Egyptian counterpart for violence at Saturday’s World Cup game in Cairo.
At least 32 people were hurt following the match, and the following day Egyptian businesses in Algiers were ransacked..
After Egypt’s 2-0 victory left their group deadlocked, the two countries face a play-off on Wednesday in the Sudanese capital, Khartoum.
Fifteen thousand Sudanese police are being deployed to prevent trouble. There will be strict segregation of fans inside the stadium.
Before the Cairo game, three Algerian players were injured when their team bus was pelted with stones.
The head of the Algerian football federation, Mohammed Raouraoua, said his Egyptian counterpart, Samir Zaher, was to blame for the trouble.
“He is the origin of all the events that occurred, including the barbaric aggression that injured… our players,” Mr Raouraoua said.
But Egyptian Foreign Minister Ahmed Abul Gheit responded by stating that Algeria confront what he called the “saboteurs” who have attacked Egyptian businesses in Algiers.
Thousands of fans from both countries have already arrived in Khartoum for the play-off, arranged at a neutral venue by Fifa after the teams could not be separated at the top of their group.
There is a history of trouble between supporters of the two teams. Riots broke out in Egypt in 1989 after an Egyptian win in Cairo ensured that they, rather than their neighbours, qualified for the 1990 World Cup finals.
