Kenyan fans were banned from Sunday's match

Ochilo Ayacko has written to the Attorney General saying there was clear evidence of a deliberate attempt to lose the matches in favour of Tunisia.

Kenya lost both home and away matches to Tunisia and Mr Ayacko alleges they were manipulated in favour of Tunisia.

This penalised their rivals Morocco in qualifying Group Five, he said.

The sports minister was critical of the Kenyan Football Federation which is beset by political infighting.

If we fixed the game, then where's the money? Mohammed Kheri Kenya coach

The return match against Tunisia was played behind closed doors on Sunday as punishment from Fifa following crowd violence at the game against Morocco in June.

Mr Ayacko said the Fifa sanction was "outrageous" and blamed the federation for its handling of an appeal against the punishment.

He said a number of factors give rise to suspicion: the non-selection of a top player, the way the team played and suspicious goings on in the Kenyan Football Federation.

Harambee Stars coach Mohammed Kheri has described the allegations as outrageous and pure madness.

He said, "If we fixed the game, then where's the money?"

The BBC's Harry Peart says the allegations will inflame further a volatile situation within Kenyan football.

In the conflict within the Kenyan Federation the sports minister has sided with the chairman Alfred Sambu, who also has the backing of world football's governing body Fifa.

Other factions, led by the former secretary general Titus Kasuve claim they are the true administrators of Kenyan football.

Unless the wrangling and the allegations of match fixing are resolved quickly, Fifa could suspend the Federation as it did for three months last year, our reporter says.

A Fifa spokesman told BBC Sport on Wednesday that it is not the world body's policy to comment on allegations.
