BAGHDAD, Dec 22 (Reuters) - Iraq has purchased 150,000 tonnes of wheat, its trade ministry said on Thursday.

The purchase was comprised of 100,000 tonnes of Australian wheat and 50,000 tonnes of U.S. wheat, the ministry added.

European traders said the Australian wheat was believed to have been bought at an estimated $461 a tonne c&f, with trading house The Andersons believed to be the seller.

The U.S. wheat was said to have been bought at around $496 a tonne c&f, with trading house ADM believed to be the seller.

Traders had initially assessed on Wednesday that all of the wheat would be sourced from Australia.

The tender for a nominal 50,000 tonnes had closed on Dec. 18, seeking wheat sourced from the United States, Australia and/or Canada, they said.

Volumes in Iraq’s tenders are nominal and the country often buys more than sought in the tender. (Reporting by Moayad Kenany, additional reporting by Michael Hogan in Hamburg, Writing by Nadine Awadalla; Editing by Mark Potter)
