US Secretary of State John Kerry says the United States and Iran both have a "mutual interest" in defeating the IS terrorist group.
"They are totally opposed to IS and they are in fact taking on and fighting and eliminating IS members along the Iraqi border near Iran and have serious concerns about what that would do to the region," RIA Novosti cited Kerry told as saying.
"So we have at least a mutual interest, if not a cooperative effort," Kerry stated.
