In Europe, Barnett International sold crossbows to Serbian forces which according to "The Guardian" were later used "in ambushes and as a counter-sniper weapon" against the Kosovo Liberation Army during the Kosovo War in the areas of Pec and Djakovica, south west of Kosovo. Whitehall launched an investigation, though the Department of Trade and Industry established that not being "on the military list", crossbows were not covered by such export regulations. Paul Beaver of Jane's Defence Publications commented that, "They are not only a silent killer, they also have a psychological effect". On 15 February 2008, Serbian Minister of Defence Dragan Sutanovac was pictured testing a Barnett crossbow during a public exercise of the Serbian Army's Special Forces in Nis, south of capital Belgrade. Special forces in both Greece and Turkey also continue to employ the crossbow. Spain's Green Berets still use the crossbow as well.
