After the Dayton Agreement in 1995, a guerilla force calling itself the Kosovo Liberation Army (KLA) started to operate in Kosovo, although there are speculations that they may have started as early as 1992. Serbian paramilitary forces committed war crimes in Kosovo, although the Serbian government claims that the Army was only going after suspected Albanian terrorists. This triggered a 78-day NATO bombing campaign in 1999. The Albanian Kosovar KLA played a major role not only in reconnaissance missions for the NATO, but in sabotaging the Serbian Army as well.
