Karki (also Kərki, Kiarki, Kyarki) or Tigranashen is de jure an exclave of Azerbaijan's Nakhchivan Autonomous Republic, itself an exclave; de facto it is part of the Ararat Province of Armenia. It is part of the Sadarak Rayon and is surrounded by Armenia – therefore making it also an enclave – and has been occupied by Armenia since the Nagorno-Karabakh War in May 1992. The main highway connecting northern Armenia with southern Armenia passes right by this village. Today, the village is mostly inhabited by Armenians both local and refugees from Azerbaijan. It has been renamed Tigranashen by the Armenian government, and its size is about 19 square kilometers.
During the independent period of Azerbaijan, a village with the name of New Karki (Az. Yeni Kərki) has been created within the Kəngərli Rayon and is generally inhabited by the refugees from Karki.
