:::It is the flag of the country Serbia, not the flag of the claimed Province. You have yet to achieve a consensus to insert this flag into the article, I suggest you remove it until gain a consensus.  
 :::It is POV to refer to Kosovo as a 'Province' because it is DISPUTED! It is disputed as to whether APKIM exists.  
 :::"In 2003, the Federal Republic of Yugoslavia was renamed the State Union of Serbia and Montenegro. In 2006, Montenegro left the federation, while Serbia became its legal successor. The official status of the Kosovo province in the Serbian legal framework remained unchanged." Is this even true? If it is then please verify it. If it can't be verified then it has no place in this article. Please provide a reference if you want it to remain in the article.
