Mohamed bin Hammam, president of the Asian Football Confederation, has criticised the Sunday Times investigation into alleged corruption in bidding to host the 2018 and 2022 World Cup finals.

Two committee members - Nigeria's Amos Adamu and Rynald Temarii from Tahiti - have been suspended by Fifa after the British newspaper claimed they were willing to accept money in for their vote.

Fifa are also investigating claims of collusions between bids, believed to be the Spain/Portugal bid for 2018 and Qatar's 2022 campaign.

Bin Hammam, a Qatari, suggested reporter's posing as businessmen and using hidden cameras to record meetings was "unethical".

"Forging identity, fabricating evidence and setting traps are unethical behaviours in my point of view. One thing about Middle East media, these are rare happenings there," he said.

"Is it ethical to use unethical measures to protect the ethic? How can we serve justice and look for fairness by not acting justly and fairly? How will we clean dirty laundry by using dirty water?"
