Liberation Army of Preševo, Medveđa and Bujanovac

The Liberation Army of Preševo, Medveđa and Bujanovac (LAPMB; Albanian: Ushtria Çlirimtare e Preshevës, Medvegjës dhe Bujanocit, UÇPMB; Serbian: Ослободилачка војска Прешева, Медвеђе и Бујановца, ОВПМБ, romanized: Oslobodilačka vojska Preševa, Medveđe i Bujanovca, OVPMB) was an Albanian militant insurgent group fighting for separation from the Federal Republic of Yugoslavia for three municipalities: Preševo, Medveđa, and Bujanovac, home to most of the Albanians in south Serbia, adjacent to Kosovo.

[3][4] The UÇPMB's uniforms, procedures and tactics mirrored those of the then freshly disbanded Kosovo Liberation Army (KLA).

The 1,500-strong paramilitary launched an insurgency in the Preševo Valley from 1999 to 2001, with the goal of joining these municipalities to Kosovo.

[8] Starting in 1998, the KLA was involved in frontal battle, with increasing numbers of Yugoslav security forces.

Ethnic Albanian politicians opposed to the KLA were attacked, including Zemail Mustafi, the vice-president of the Bujanovac branch of Slobodan Milošević's Socialist Party of Serbia who was later assassinated.

[22][23] On 13 May 2001, the VJ and Serbian police launched an attack on the UÇPMB in Oraovica before they entered Sector B.

[29] After Shefket Musliu signed the Končulj Agreement, he stated:[30] "I can tell you that we have handed over our weapons, and that the time has come to end the war.

"As the situation escalated, NATO allowed the VJ to reclaim the GSZ on 24 May 2001, at the same time giving the UÇPMB the opportunity to turn themselves over to the Kosovo Force (KFOR), which promised to only take their weapons and note their names before releasing them.

[31] With the signing of the Končulj Agreement in May 2001, the former KLA and UÇPMB fighters next moved to western Macedonia where the NLA was established, which fought against the Macedonian government in 2001.
