ALBANIA, a small Balkan country wedged between the former Yugoslavia and the Adriatic sea, is in the throes of a people's revolt—torn by violent protests, rising death toll and a strong insurrectionist movement. Thousands of enraged Albanians are demanding the resignation and ouster of right-wing democratic President Sali Berisha. "We shall overthrow the government at all costs," shouted protesters in the southern Adriatic city of Vlore where buildings were set on fire and military installations looted for weapons. Several parts of the south are out of government control.
