On 3 August 1995, the Croatian Armed Forces with the help of Bosnian Croats began shelling Drvar, from the mountain of Šator. Two Drvar citizens were killed and older men and women began to evacuate to Petrovac. One day later, the Croatian Government armed forces began "Operation Storm", called by European Union Special Envoy to the Former Yugoslavia Carl Bildt, "the most efficient ethnic cleansing we've seen in the Balkans", in the "Dalmatinska zagora" region of Croatia, and columns of hundreds of thousands of refugees in cars, on tractors, wagons and on foot began to pass through Drvar as they fled their homes in Croatia. The shelling on the outlying areas of Drvar by Croatian Government forces was renewed and continued for days.
