Why is "2014 Kalbajar incident" trending?

Wikipedia Overview

2014 Kalbajar incident refers to the crossing of a small group of Azerbaijanis into Kalbajar district, their subsequent capture and conviction for murder and sabotage by the Republic of Artsakh. In July 2014, three ethnic Azerbaijanis crossed Nagorno-Karabakh Line of Contact in to Kalbajar District, then controlled by breakaway Republic of Artsakh forces. This was followed by disappearance of 17-year-old local Smbat Tsakanyan who was later found dead from gunshot wounds and who was last seen walking with the Azerbaijanis in a video used as evidence in the trial. The Azerbaijanis were detained for "reconnaissance operations in the area on orders from Azerbaijan’s intelligence service," as well as kidnapping and killing of Tsakanyan. One of the Azerbaijanis named Hasanov attacked Major Sargis Abrahamyan and his companion Karine Davtyan on the road from Vardenis to Kalbajar, killing the first and wounding the latter, himself subsequently killed in firefight with Artsakh Defence Army servicemen. The Artsakh forces detained and convicted Asgarov and Guliyev for murdering Tsakanyan while Hasanov was posthumously convicted for killing Abrahamyan and wounding Davtyan. Asgarov and Guliyev pleaded not guilty, claiming they had crossed to Kalbajar "to visit their relatives' graves". The incident may have been a trigger of the 2014 Armenian–Azerbaijani clashes in late July and early August that year. After ceasefire agreement ended the 2020 Nagorno-Karabakh war, Armenia returned Asgarov and Guliyev to Azerbaijan, as part of a prisoner exchange.
