The head of the Algerian football federation¹ has blamed his Egyptian counterpart for violence at Saturday's World Cup game in Cairo.

阿尔及利亚足球联盟首领谴责星期六在开罗世界杯足球赛上发生的暴力事件。

Thousands of Sudanese police are on duty to prevent fresh violence

At least 32 people were hurt following the match, and the next day Egyptian businesses in Algiers were ransacked（彻底搜索，洗劫）.

Egypt has stepped up its complaints about the attacks.

After Egypt's 2-0 victory left their group deadlocked²（僵局，停顿）, the two countries face a play-off on Wednesday in the Sudanese capital, Khartoum.

Fifteen thousand Sudanese police are being deployed³ to prevent trouble.

There will be strict segregation⁴（隔离，种族隔离） of fans inside the stadium.

The capacity has been cut by 6,000 - to 35,000 - and supporters of each side will get 9,000 seats each.

High stakes

Before the Cairo game, three Algerian players were injured when their team bus was pelted⁵（投掷，攻击） with stones.

Algeria's coach, Rabah Saadane, has claimed his team's defeat was due to injuries sustained by（由于……蒙受损失） his players.

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 aggression⁶ that injured... our players," Mr Raouraoua said.

But Egyptian Foreign Minister Ahmed Abul Gheit has in turn told Algeria it must confront what he called the "saboteurs（破坏分子）" 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（中立的） venue⁷ by football's governing body Fifa after the teams could not be separated at the top of their group.

Sudanese officials say they are expecting 48 flights from Algeria and 18 from Egypt. A further 2,000 Egyptian fans are expected to travel by road.

Hotels in Khartoum are already booked out ahead of the game, and the authorities have set up two camp sites for rival fans several miles apart.

The stakes for each country are high. The last time either team was in the World Cup finals was 1990 for Egypt, and 1986 for Algeria.

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.
