Aleksinsky District (ru|Але́ксинский райо́н) is an administrative district (raion), one of the twenty-three in Tula Oblast, Russia.[1] It is located in the northwest of the oblast. The area of the district is 982.5km2.[2] Its administrative center is the town of Aleksin. Population: 74,326 (2010 Census); The population of Aleksin accounts for 83.1% of the district's total population.
On the night of 8–9 November 2024, during the Russo-Ukrainian War, Ukraine launched a drone attack on the Aleksin Chemical Plant—part of the state corporation Rostec—in the Aleksinsky District, about south of Moscow, causing a series of explosions and fires at the plant which manufactures ammunition and explosives for the Russian military. Russian sources did not acknowledge the attack's success, "as is common following a reported attack by Ukraine on one of [Russia's] military sites."[3] [4]
Within the framework of administrative divisions, Aleksinsky District is one of the twenty-three in the oblast. The town of Aleksin serves as its administrative center.
As a municipal division, the territory of the district is split between two municipal formations—Aleksin Urban Okrug,[5] to which the town of Aleksin and 154 of the administrative district's rural localities belong,[6] and Novogurovsky Urban Okrug,[7] which covers the rest of the administrative district's territory, including the work settlement of Novogurovsky.[8]
