evidence: The issue of exclaves/enclaves is another border-related issue; there is an exclave called Artsvashen which is formally part of Soviet-era Armenia but controlled by and situated entirely within the current Republic of Azerbaijan; likewise, there are 4 Azerbaijani exclave villages of Karki, Yukhari Askipara, Barxudarlı and Sofulu that were formally part of Soviet-era Azerbaijan but are controlled by and situated entirely within the current Republic of Armenia.[87] [...] April 2024 [edit]In April 2024, Armenia and Azerbaijan reached an agreement whereby Armenia handed over four abandoned villages along the border to Azerbaijan: Bağanis Ayrum, Aşağı Əskipara, Xeyrimli, and Qızılhacılı.[259] The four villages were on the Azerbaijani side of the border and had been controlled by Armenia since the First Nagorno-Karabakh War.[260] The two countries agreed to demarcate the borders on the basis of Alma-Ata declaration, which fixed the borders that existed between the former Soviet republics. This sparked protests among some residents of the neighboring villages of Tavush province.[85] The agreement was welcomed by the U.S. Secretary of State Antony Blinken,[261] President of the European Council Charles Michel,[262] on behalf of the UN Secretary-General António Guterres, his spokesperson Stéphane Dujarric.[263] On May 24, 2024, the State Border Service of Azerbaijan took control of the four villages.[86][264]
