As many as 100,000 Yugoslavs defied Communist leaders to stage the latest of a series of anti-Albanian rallies in support of bringing an autonomous southern region under Serbian control. The protest in Novi Sad, in Vojvodina province, was held despite official pleas to stop the rallies, which began there in July. They were sparked by alleged persecution of Slavs by ethnic Albanians in autonomous Kosovo province. The protesters carried banners supporting Serbian Communist Party leader Slobodan Milosevic. He is pressing for constitutional reforms to return Serbia’s two autonomous provinces--Kosovo and Vojvodina--to central Serbian control.
