For three decades multiple violations of the ceasefire occurred, the most serious being the four-day 2016 Nagorno-Karabakh conflict. Surveys indicated that the inhabitants of Nagorno-Karabakh did not want to be part of Azerbaijan, and in August 2019, in a declaration in favour of unification, the Armenian prime minister Nikol Pashinyan stated "Artsakh is Armenia, full stop". Further skirmishes occurred on the border between Armenia and Azerbaijan in July 2020.
