Sokolohirsk

Pervomaisk (Ukrainian: Первомайськ, IPA: [perwɔˈmai̯sʲk] ; Russian: Первомайск), also known as Sokolohirsk (Сокологірськ), is a city in Luhansk Oblast, Ukraine, on the left bank of the Luhan River. Pervomaisk is located 71 kilometres (44 mi), by road, from Luhansk, 133 kilometres (83 mi) from Izvaryne, where there is the de jure international border between Ukraine and Russia, and 736 kilometres (457 mi) from the capital Kyiv.

Pervomaisk came under the control of the breakaway Luhansk People's Republic (LPR) in early 2014, following which the city became a focal point of the war in Donbas, sustaining heavy destruction in the conflict. In 2022, Russia declared its annexation of the entirety of Luhansk Oblast, including Pervomaisk, as part of the LPR. The population of Pervomaisk is 36,091 (2022 estimate).
