Australia has become the latest country to join the U.S.-led military campaign against militants from the Islamic State in Iraq and Syria. Prime Minister Tony Abbott said Australian planes will take part in airstrikes and that special forces would be deployed in Iraq. Turkey’s Parliament has also backed the effort, authorizing the government to order military action against the militants. The news comes as Iraq’s defense minister claimed Iraqi forces have made gains against ISIS, retaking 30 villages east of Baghdad.
