Listen arce, all parties were wrong in this war, we re discussng here who bombed the market? its actually not important, considering you need to know the whole agenda behing yugoslavia. But ill try to anwser, there is no proof to this day who bombed it, but at that time, bosnians were taking ground from the serbs,, it wasnt in the interest of bosnians to end the war at that time.
Before you want to know what why and what really happened there you need 120 hours of research. Its too big to explain, but its connected to the british, just like the brits are in charge of america. btw tito was a british agent.
