Martuni or Khojavend is a town in Khojavend District of Azerbaijan, in the region of Nagorno-Karabakh. After the First Nagorno-Karabakh War, it came under the de facto control of the breakaway Republic of Artsakh as the centre of its Martuni Province. The town returned to Azerbaijan's control after the 2023 Nagorno-Karabakh offensive.

Between 19 and 20 September 2023, Azerbaijan launched a large-scale military offensive against the self-declared breakaway state of Artsakh, a move seen as a violation of 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. The stated goal of the offensive was the complete disarmament and unconditional surrender of Artsakh, as well as the withdrawal of all ethnic Armenian soldiers present in the region. The offensive occurred in the midst of an escalating crisis caused by Azerbaijan blockading Artsakh, which has resulted in significant scarcities of essential supplies such as food, medicine, and other goods in the affected region.
