evidence: The Ungar-Too (also: Ungar-Tepe) is a mountain located on the Kyrgyzstan–Uzbekistan border, which has been a cause of tension between the two countries. [...] The Uzbek presence on the mountain remained for the time being and was increased to 20 people at the beginning of September 2016. The occupation of the Ungar-Too was also used as leverage in other acute issues, but bilateral negotiations initially remained unsuccessful. The four Kyrgyz workers were held in a police station in Yangikurgan.[4] The diplomatic efforts eventually led to the release of the prisoners and the evacuation of the mountain on 18 September.[5] In the months to come, the two countries came closer together and a Kyrgyz diplomatic delegation visited Uzbekistan for the first time in several years. In July 2018, an agreement was concluded between the states that clarified some border issues, but the Ungar-Too was not mentioned in it, so that status remains unclear.[6][7]
