Fifa has provisionally suspended two top officials in a World Cup vote-selling scandal.
The Nigerian and the Tahitian are barred from football-related duty until the probe ends.
The two executive members offered to sell votes in the bidding for the 2018 and 2022 World Cups.
"We are determined to have zero tolerance for any breach of the code of ethics," Claudio Sulser, chairman of Fifa’s ethics committee said.
The executives were filmed by undercover reporters from the Sunday Times newspaper of Britain asking for money for football-related projects.
Fifa said investigations were also under way into "other Fifa officials" who may have been involved.
Fifa will choose two World Cup hosts in a secret ballot scheduled for December 2 in Zurich. The 2018 race is between four European candidates: England, Russia and joint bids from Belgium-Netherlands and Spain-Portugal.
The 2022 contest is between the United States, Australia, Japan, Qatar and South Korea.
