In October 1999 when Kosovo Forces (KFOR) entered the Province of Pristina, they were immediately confronted with the problems encountered by a population returning through areas contaminated by unexploded, NATO-dropped, cluster munitions (CBU). NATO advised that as many as 333 areas had been bombarded with such aerial delivered weapons. They found the problem extended to more than 600 mine fields left by the Serbian Army (VJ), Police (MUP), and other paramilitary forces. These were principally along the border with Albania and the Federal Yugoslav Republic of Macedonia (FYROM) and scattered in other strategic areas on the interior.
