Ethnic strife boiled over in southeastern Yugoslavia Saturday, as 65,000 Serbs and Montenegrins took to the streets to demand an end to Albanian extremist violence and a communist-party house-cleaning.

Ratko Licina, president of the Smederevo Socialist Alliance, called on Yugoslavia's communist authorities to "immediately secure conditions that Serbs (and) Montenegrins can live in peace and freedom in Ko-sovo," an autonomous province that is nearly 90 percent ethnic Albanian.Following the two-hour rally, protesters cabled the Yugoslav Socialist Alliance to demand authorities "guarantee freedom and human rights for all inhabitants" of Kosovo, a province within Serbia, largest of Yugoslavia's six republics.
