In 2004, prolonged negotiations over Kosovo's future status, sociopolitical problems and nationalist sentiments resulted in the Kosovo riots. Organised and spontaneous acts of violence and damage by Kosovar Albanians was directed at properties of the Serbs, their churches and the Romani leaving some dead and many displaced. International legal precedents based on territorial sovereignty overriding self-determination were brushed aside in the case of Kosovo when parts of the international community recognised the declaration of Kosovan independence (2008). This was put down to fears that not doing so would result in Albanian nationalism possibly making the situation difficult and worse for the international community in Kosovo had conflict eventuated. Albanian nationalism is viewed in the Balkans as having furthered events in Kosovo which has caused concerns about the phenomenon of nationalism and generated fears among Serbs, Croats, Macedonians, Romanians and Bulgarians. The ending of the Kosovo war resulted in the emergence of offshoot guerilla groups and political organisations from the KLA continuing various violent struggles. In the Preševo valley the "Liberation Army of Preševo, Medveđa and Bujanovac" (UÇPMB) fought Serb forces (1999-2001) attempting to unite the area with neighbouring Kosovo with conflict ending in peace talks and greater Albanian rights in Serbia. In northern parts of the Republic of Macedonia the "National Liberation Army" (NLA) fought against Macedonian forces (2001) with conflict ending in peace talks and the signing of the "Ohrid Agreement" granting greater Albanian rights in Macedonia.
