Yugoslavia's political and social strife as it transforms from a former communist nation to a fractured Balkan state.
Rebel forces say they're fighting for greater rights for the ethnic Albanian minority in Macedonia.
But the government fears the true goal of the rebels is to split off northern Macedonia and form an independent state with Kosovo, where ethnic Albanians are the majority. Two civilians were killed and 10 others wounded in the assault on the village of Krivenik, just 1,200 yards inside the Kosovo border, said U.S. Maj. James Marshall, spokesman for U.S. forces in Kosovo. No peacekeepers were reported injured. Helicopters thundered overhead.
