FARS News Agency, Iran Tuesday Iran Cautions Rising Tensions Between Armenia, Azerbaijan Over Nagorno-Karabakh Region TEHRAN (FNA)- Iranian Foreign Ministry Spokesman Bahram Qassemi voiced concern over the escalation of tensions between Azerbaijan and Armenia over the Nagorno-Karabakh region, and said that the increase in conflicts is not in the interest of Azeri and Armenian people. "Iran will spare no efforts to decrease tensions in this region," Qassemi said. The Iranian foreign ministry spokesman expressed the hope for restoration of peace and stability in the region and cautioned about enemy's plots for provoking violence. In relevant remarks in January 2015, Iranian Foreign Minister Mohammad Javad Zarif reiterated that the Nagorno-Karabakh dispute between Azerbaijan and Armenia can be resolved only through political solutions. "We hope that the (Nagorno-) Karabakh dispute will be resolved only through compliance with the international laws and talks between the two sides," Zarif said in Yerevan. He further reiterated that Iran wishes peace and stability for its neighbors. Despite facing strong international pressure, the Armenian and Azerbaijani leaders have failed to agree on the basic principles of ending the Nagorno-Karabakh conflict put forward by Russia, the United States and France in 2011. Armenia and Azerbaijan thus remain officially at war over Nagorno-Karabakh and the dispute is a major source of tension in the South Caucasus region wedged between Iran, Russia and Turkey. No country - not even Armenia - officially recognizes Karabakh as an independent state. The mountainous rebel region has been controlled by ethnic Armenians since it broke free of Baku's control after a fierce war in the early 1990s that killed 30,000 people.
