During the present war against the Republic of Croatia, chemical weapons have been used by the Yugoslav Federal Army (YFA) against both civilians and Croatian Army soldiers. The use of irritants was suspected (Vukovar, Bogdanovci and Vinkovci, October-November, 1991; Solin in the Split area, September, 1991) and proved (Velika Gorica in the Zagreb area, September, 1991; Cakovec, November, 1991) in many cases. The use of psychochemical incapacitating agents (Bilje near Osijek, July, 1991), as well as of psychostimulants in YFA own soldiers (Zadar, August, 1991) has been suspected on clinical findings or laboratory tests. The use of acetylcholnesterase inhibitors was proved in one aggressor's diversion (Zadar, Krusevo, July, 1991). Phosphorus from projectiles and fuming boxes caused poisoning and skin burns due to incineration (Vukovar, November, 1991). YFA used the civilian's fear of chemical and biological weapons, throwing untoxic substances all over the Croatian territory. Great ecocide problems have occurred with massive industry devastation (Sisak, Osijek, October, 1991-January, 1992), with enumerous amounts of toxic substances released into the soil and river aquatoria.
