FIFA ethics prosecutor Michael Garcia is interviewing Sepp Blatter and other voters who chose 2018 and 2022 World Cup hosts Russia and Qatar

FIFA says Garcia "is currently in Zurich and is also interviewing some of the FIFA executive members as part of his ongoing work."

Blatter and 11 colleagues, including UEFA president Michel Platini and Russian sports minister Vitaly Mutko, remain on FIFA's board from the December 2010 vote.

Among 10 voters who left FIFA, Mohamed bin Hammam of Qatar was banned for life for financial wrongdoing.

Garcia's investigating team is focusing on FIFA board members after seeking interviews since last October with officials from the nine World Cup bid committees.

Garcia's law firm in New York has said his investigation should extend "at least several months into 2014."
