The Yugoslav People's Army begins the Ten-Day War in Slovenia.

The Ten-Day War (Slovene: desetdnevna vojna), or the Slovenian War of Independence (slovenska osamosvojitvena vojna), was a brief armed conflict that followed Slovenia's declaration of independence from Yugoslavia on 25 June 1991. It was fought between the separatists of the Slovenian Territorial Defence and the Yugoslav People's Army (or JLA). It lasted from 27 June 1991 until 7 July 1991, when the Brioni Accords were signed.

It was the second of the Yugoslav wars to start in 1991, following the Croatian War of Independence, and by far the shortest of the conflicts with fewest overall casualties.

The Yugoslav People's Army (abbreviated as JNA; Serbian: Југословенска народна армија, ЈНА / Jugoslovenska narodna armija, JNA; Croatian: Jugoslavenska narodna armija, JNA; Bosnian: Jugoslavenska narodna armija, JNA; Slovene: Jugoslovanska ljudska armada, JLA; Macedonian: Југословенска народна армија, ЈНА, romanized: Jugoslovenska narodna armija, JNA), also called the Yugoslav National Army, was the military of Socialist Federal Republic of Yugoslavia and its antecedents from 1945 to 1992.
