The U.S. State Department warns that al-Nusra terrorists use chemical weapons in Syria. Russian's defence ministry says it's the first admission of its sort - after years of allegations that only the Assad government carries out chemical attacks in Syria. Vladimir Putin says Russia will take retaliatory measures against the U.S. - if Washington continues to crack down on Russian media in America.  Friends or foes - Washington stresses the importance of a unified Iraq, despite its support for Kurdish forces, which are seeking independence.
