CANBERRA, Australia (AP) _ An Australian held hostage for four weeks in Iraq has been freed in a military operation, Australian Prime Minister John Howard announced Wednesday.

Howard told Australia's Parliament that the hostage, Douglas Wood, was ``safe.''

``Mr. Wood was recovered a short while ago in Baghdad in a military operation that I am told was conducted by Iraqi forces in cooperation in a general way with force elements of the United States,'' Howard said, according to the Australian Broadcasting Corp.
