2023 Azerbaijani offensive in Nagorno-Karabakh

On 19 and 20 September 2023, Azerbaijan launched a large-scale military offensive against the self-declared breakaway state of Artsakh, violating the ceasefire agreement signed in the aftermath of the Second Nagorno-Karabakh War in 2020. The offensive took place in the disputed region of Nagorno-Karabakh, which is de jure a part of Azerbaijan, and was a de facto independent republic.
