Bosnian improvised rifle-grenades filled with acid

[goran_croatia]

I red in one article about the serbian agression on Sarajevo from 1992-1995 that Bosnian army located in Sarajevo during serbian siege of the city was using improvised rifle grenades filled with acid.The article says that those rifle-grenades were made in the city during the serbian siege and that rifle grenades were some kind of bottle filled with acid.After been fired,when that rifle grenade hit the serbian positions,it would explode(bottle which was the top of that rifle-grenade would be broken)and the acid would sprinkle around the place of impact.All enemy soldiers near the place of impact would be wounded with acid burn.

I was googled,but nothing,just that info in one article,does any of you have any information or pics of that bosnian army improvised rifle-grenades?
