to such an extent that it was sometimes, according to the International Criminal Tribunal for the former Yugoslavia (ICTY) documentation in subsequent war crimes trials, "difficult to distinguish between the two groups". For that reason, the ICTY has used the term "Mujahideen" (which they spell Mujahedin) for both fighters from Arab countries, and also local Muslims who joined the mujahideen units. They quickly attracted heavy criticism from people who claimed their presence was evidence of violent Islamic fundamentalism in Europe. The foreign volunteers even became unpopular with many of the Bosniak population, because the Bosnian army had thousands of troops and had no need for more soldiers, but rather for arms. Many Bosnian Army officers and intellectuals were suspicious of the foreign volunteers arrival in the central part of the country, because they came from Split and Zagreb in Croatia, and were passed through the self-proclaimed Croatian Community of Herzeg-Bosnia without problems, unlike Bosnian Army soldiers who were regularly arrested by Croat forces. The first mujahideen training camp was located in Poljanice next to the village of Mehurici, in the Bila valley, Travnik municipality. The mujahideen group established there included mujahideen from Arab countries as well as some Bosniaks. The mujahideen from Poljanice camp were also established in the towns of Zenica and Travnik and, from the second half of 1993 onwards, in the village of Orasac, also located in the Bila valley. The military effectiveness of the mujahideen is disputed. However, former U.S. Balkans peace negotiator Richard Holbrooke said in an interview that he thought "the Muslims wouldn't have survived without this" help, as at the time a U.N. arms embargo diminished the Bosnian government's fighting capabilities. In 2001, Holbrooke called the arrival of the mujahideen "a pact with the devil" from which Bosnia still is recovering. On the other hand, according to general Stjepan Šiber, the highest ranking ethnic Croat in the Bosnian Army, the key role in foreign volunteers arrival was played by Tuđman and Croatian counter-intelligence with the aim to justify the involvement of Croatia in the Bosnian War and the crimes committed by Croat forces. Although the Bosnian President Alija Izetbegović regarded them as symbolically valuable as a sign of the Muslim world's support for Bosnia, they appear to have made little military difference and became a major political liability. Sakib Mahmuljin, a top Bosnian general, has stated that the mujahideen sent 28 severed heads
