 During the Kosovo crisis, the Macedonian Air Warfare and Air Defence Forces relocated all its aircraft to relatively safe locations, deep within Macedonian territory, from where it was actively involved in monitoring the troubled borders with Kosovo and Albania, as well as supplying a number of Kosovar Albanian refugee camps with food, water, and medical care.After the withdrawal of Yugoslav Army from Kosovo and the deployment of KFOR in Kosovo, the UN began the process of disarming the Kosovo Liberation Army (KLA).Beginning in spring 2000, Albanian insurgents launched a large scale of frontal assaults on police stations, checkpoints, and border outposts in southern Serbia and Macedonia.
