evidence: Located just north of the Aras River and the Iranian border, Meghri is hemmed in by Azerbaijani territory. To the east lies Azerbaijan proper, whose border with Armenia has been shut since 1991. Roughly six miles to the west lies Nakhchivan, a landlocked Azerbaijani exclave that Baku has long dreamed of connecting to its mainland. A sliver of Nakhchivan borders Turkey. [...] Yerevan pledged to open transport routes to Baku as part of a 2020 cease-fire after a brief war in Nagorno-Karabakh. But since then, Armenian officials have balked, saying that any such arrangement would effectively be the occupation of Armenian territory. [...] But in 1992, with Armenia and Azerbaijan at war over Nagorno-Karabakh, revenge attacks escalated. A group of Azerbaijanis hijacked the train running from Yerevan to Kapan as it passed through Nakhchivan and took 12 wagons full of mostly Armenian passengers hostage for a week.
