Iran toughened Thursday its criticism of Turkey over its plan to host an early-warning radar as part of NATO’s missile defence system, saying it will create tension and lead to “complicated consequences.” “We expect friendly countries and neighbours … not to promote policies that create tension, which will definitely have complicated consequences,” foreign ministry spokesman Ramin Mehmanparast said in remarks carried by the state television website. “We believe that the installation of some parts of the NATO missile system in Turkey will not help the security and stability of the region at all, nor that of the host country,” Mehmanparast said. Iran “condemns any action that creates an arms race in the world and region,” he added.
