BBC News reports the U.S. has carried out its first air strike against Islamic State (IS) militants under a new strategy to "degrade and destroy" the group. U.S. officials said the strike destroyed an IS fighting position near Baghdad, five days after President Obama outlined his new anti-IS strategy. IS has seized large areas of Syria and Iraq and declared a "caliphate." Meanwhile, Iraq's new PM saw his two nominations for defence and interior minister rejected by parliament. The rejections of the two key posts are a setback for Prime Minister Haider al-Abadi. The U.S. has also been building a broad coalition to fight the jihadist group, which is also known as Isil or Isis.
