Kosovo is part of Serbia
that wants to be a separate country. Kosovo has always been part of Serbia, and there are some of the oldest Serbian churches that are currently under protect, they are about 90% of oldest saved Serbian culture.
For people who say Kosovo is part of Albania, they are deadly wrong. if you dig a bit in history, you will find that Albania was part of Serbia that under the influence of big powers became separate country. Great powers tryed to prevent Serbia from getting powerful.
Kosovo is now days (October '11) trying to get their own country by blocking roads and using warnings. Since Serbia (along with couple other countries, for ex: Russia) said they will never support idea of Kosovo becoming country, the "case" will be open for a long time.
Kosovo will never be its own.
