Yugoslav dinar experienced a major hyperinflation, leading to inflation reaching 313 million percent, the second worst hyperinflation in history. Many parts of FR Yugoslavia, including all of Montenegro, adopted the Deutsche Mark and Euro currencies instead of the Yugoslav dinar. Western sanctions crippled the Yugoslav economy, and prevented it from playing an active role in aiding Serb breakaway republics. Following the Dayton Agreement, the UN Security Council voted to lift most sanctions, but they were reissued following the outbreak of an Albanian insurgency in Kosovo. The lasting economic impact can be attributed to the eventual downfall of FR Yugoslavia and Slobodan Milošević's government, as well as a deeper desire in Montenegro to leave Yugoslavia. Kosovo War In the Autonomous Province of Kosovo and Metohija, a growing desire for independence emerged among the Albanian majority population. Already, an unrecognised Republic of Kosova had emerged with underground institutions. In 1996, the Kosovo Liberation Army, an Albanian militia promoting Kosovar independence, launched attacks against Serbian police stations, killing at least ten Serbian policemen in direct attacks between 1996 and 1998. The low level insurgency eventually escalated. After Slobodan Milošević was elected President of Yugoslavia in 1997, having served his maximum two terms as President of Serbia, he ordered JNA units to move into Kosovo to aid in the suppression of the insurrection. The governments of FR Yugoslavia and the US declared the Kosovo Liberation Army a terrorist organisation, following repeated deadly attacks against Yugoslav law enforcement agencies. US intelligence also mentioned illegal arms sources of the Kosovo Liberation Army, including conducting raids during the course of the Albanian Civil War, and drug dealing. Despite this, substantial evidence now shows that the CIA had aided in training units of the KLA, although not necessarily providing them with arms and funding. In 1998, the Kosovo War began, following increased open combat with Yugoslav police and JNA units deployed by Milošević. The KLA found itself heavily outnumbered and outgunned in open combat, and had to use guerrilla tactics. Serbian police and JNA units attacked KLA outposts, attempting to destroy them, as KLA units attempted to avoid direct confrontation and use terrorist attacks, including bombings and ambushes, to weaken Yugoslav control. Although unable to gain a strategic advantage, Yugoslav Army units found themselves in a tactical advantage against KLA units which lacked proper training. JNA units themselves lacked morale, and attacks were often directed against civilian targets
