After four years of heavy fighting in Nagorno-Karabakh, the civil war has now also spilled into Nakhichivan, an Azerbaijani enclave to the south which is isolated from the rest of Azerbaijan by Armenia to the noth, and Turkey and Iran to the south. The hostilities broke out around May 4 when three people was killed in the first Armenian attack of Nakhichivan, and have escalated subsequently. The heaviest fighting there took place on May 18 when it is reported that Armenian forces captured the hills surrounding the town Sadarak using rockets and shells, allegedly leaving as many as twenty Azerbaijanis dead and 120 injured. Armenian authorities have denied any official Armenian involvement, maintaining that the Armenian advances are being perpetrated by irregulars. The President of Nakhichevan Majlis (parlament), Geidar Aliyev, declared a unilateral ceasefire on May 23 and now apparantly is seeking to conclude a separate peace the Armenia, although the legality of these efforts has been contested. Armenian President Levon Ter-Petrossian has expressed his willingness to sign a cooperation treaty with the Republic of Nakhichevan to end the fighting.
