Austrian officials say former top U.S. diplomat Zalmay Khalilzad is being investigated by U.S. authorities for suspected money laundering through his wife's bank account.

State prosecutor Thomas Vecsey on Monday confirmed a report by the Austrian weekly Profil but declined to give details.

The magazine says the suspicions center on the alleged transfer of 1.15 million euros (about $1.5 million) in May 2013 to an account in Vienna owned by Cheryl Benard. It says the money came from Mideast business activities, adding documents on the case were found in a garbage container used by the state prosecutor's office in Vienna.

Khalilzad was ambassador to Afghanistan, Iraq and the U.N. under President George W. Bush.

Benard's lawyer, Holger Bielesz, says that U.S. authorities have yet to express "reasonable grounds for suspicions."
