Drone attacks targeted industrial areas around Nevinnomyssk in Russia's Stavropol region on May 20, according to Governor Vladimir Vladimirov [1]. Nevinnomyssk hosts the large chemical plant Nevinnomyssky Azot, which has been targeted previously by drone strikes attributed to Ukraine [1].

Earlier, on May 17, two industrial sites caught fire following drone attacks in the Nizhny Novgorod region [2]. Local authorities are conducting firefighting efforts and assessing damage and casualties, though no specific casualty numbers or damage assessments have been reported yet [2].

Russia has frequently reported recent drone attacks targeting energy and industrial facilities within its territory, linking these strikes to Ukrainian forces [2]. Both Ukraine and Russia deny deliberately targeting civilians amid their ongoing conflict [1].

The Nizhny Novgorod and Stavropol incidents represent separate drone strikes days apart, with differing locations but both hitting industrial infrastructure [1, 2]. Authorities continue investigations and damage assessments following these attacks.

Firefighting and damage evaluation operations remain underway in the Nizhny Novgorod region after the May 17 attacks [2]. Officials in Stavropol region have confirmed the May 20 strikes near Nevinnomyssk [1].
