Iranian Foreign Minister Manuchehr Mottaki said on Wednesday that a threat against Turkey would amount to a threat against Iran and vice versa, Anadolu Agency reported.
Turkey's Foreign Minister Ahmet Davutoglu and Motaki held a press conference after holding a meeting in Ankara.
Replying to a question, Mottaki said Tehran's research reactor would need fuel within a year.
Foreign Minister Motaki said swapping low-enriched uranium with uranium enriched by 20 percent was a formula which could build confidence.
Motaki said there was a great cooperation in several areas between Turkey and Iran, noting that the two countries had a common point of view regarding security issues in the region.
He added that any threat to the security of Iran amounts to a threat to the security of Turkey.
