On March 24, 1999 the NATO military operation against the Federal Republic of Yugoslavia began. The operation sought to stop human rights abuses in Kosovo, but was not authorized by the UN. The airstrikes lasted until June 10, 1999. The NATO bombing campaign marked the second major combat operation in its history, following the 1995 NATO bombing campaign in Bosnia and Herzegovina. The 1999 operation resulted in the withdrawal of Yugoslav forces from Kosovo and the establishment of UNMIK, a UN mission in Kosovo.
