Sievierodonetsk (Ukrainian: Сє́вєродоне́цьк; Russian: Северодонецк, Severodonetsk) is a city in the Luhansk Oblast of Ukraine. Sievierodonetsk has the status of a city of oblast significance, It is located nearby the Seversky Donets River, approximately 110 km (68 mi) to the north north west from the Oblast capital, Luhansk. Severodonetsk is the acting administrative centre of Luhansk Oblast due to Luhansk being temporarily controlled by self-proclaimed pro-Russian separatist organization, not under control of the Ukrainian authorities, similarly to Mariupol acting as the administrative center of Donetsk Oblast during the Russian military intervention in Ukraine (2014–present). Population: 109,466 (2013 est.).
Sievierodonetsk has several factories and a significant chemical production centre "Azot" (English translation: Nitrogen). There is a domestic airport in a nearby city.
During the 2014 pro-Russian unrest in Ukraine the town was captured late May 2014 by pro-Russian militants. No Ukrainian presidential election in 2014 was held in the city as the militants did not allow the voting places to open and much of the Election commission property was either stolen or destroyed. On 22 July 2014, Ukrainian forces regained control of the city. Heavy fighting continued around the city for a number of days; on 23 July 2014 the National Guard of Ukraine and the Ukrainian Army released a statement that said they were "continuing the cleansing of Sieverodonetsk".
A bridge across Siverskyi Donets river was severely damaged during the war in 2014; it was re-opened in December 2016. The European Union contributed 93.8% of the funding for the restoration.1939 – 5,000 inhabitants
