Bulgarian and British experts warned of security risks posed by large stockpiles of weapons left without proper control in the wake of military reforms in this new NATO member country. As part of its integration into NATO, Bulgaria reduced its armed forces from some 100,000 to a troop strength of 45,000, which left between 300,000 and 350,000 small arms and light weapons in surplus stockpiles, said a report published by the Bulgarian Center for the Study of Democracy and the British Saferworld group.
