The Lachin offensive (Azerbaijani: Laçına hücum əməliyyatı) was a military operation launched by Azerbaijan against the unrecognized Republic of Artsakh and their Armenian allies along the Armenia–Azerbaijan border during the Second Nagorno-Karabakh War, with the suspected goal of taking control of the Lachin corridor. The offensive began in mid-October, when the Azerbaijani forces advanced into Qubadlı and Laçın Districts after capturing Zəngilan. On 25 October, the Azerbaijani forces seized control of the city of Qubadlı.
