No Military Coordination

US national security adviser Susan Rice said on Friday the United States is not engaged in military coordination with Iran in countering Islamic State (IS) forces in the Middle East, Reuters reported.  Rice, at a White House briefing, responded to a report claiming that President Barack Obama had written a letter to Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei about Islamic State by saying, “We are in no way engaged in any coordination - military coordination - with Iran on countering ISIL.”
