Armenian armed forces launched a missile attack against the Azerbaijani city of Mingachevir late Sunday, Baku presidential aide Hikmet Hajiyev said.

The industrial city plays a key role in the area, due to its reservoir and key power plant.

"Armenia's state terror against Azerbaijani civilians continues. Minutes ago, Armenian forces launched a missile attack against #Mingachevir industrial city of Azerbaijan. Mingachevir hosts a water reservoir and key electricity plant," Hajiyev wrote on his social media account.

Azerbaijan's Defense Ministry confirmed a rocket fire against the cities of Mingachevir and Terter, reporting that people had been wounded.

There were no reports of an attack from the Azerbaijani side.

"A barbaric expression of desperation," Hajiyev twitted.

Separately, Armenia hit the Khizi-Absheron region near Azerbaijan’s capital Baku with mid-range missiles.
