Australian outlet ABC News published an article Thursday saying the United States could initiate a missile strike against Iran as early as next month.

Australian Prime Minister Malcolm Turnbull also denied the report, which cites unnamed Australian officials.

„It‘s speculation,“ Turnbull said, according to The Straits Times. „It is citing anonymous sources.“
