From the outset, both parties to the conflict violated the "safe area" agreement, although a two year period of relative stability followed the establishment of the enclave. Lieutenant colonel Thom Karremans (the Dutchbat Commander) testified to the ICTY that his personnel were prevented from returning to the enclave by Serb forces and that equipment and ammunition were also prevented from getting in. Bosniaks in Srebrenica complained of attacks by Serb soldiers, while to the Serbs it appeared that Bosnian government forces in Srebrenica were using the "safe area" as a convenient base from which to launch counter-offensives against the Army of the Republika Srpska (VRS) and that UNPROFOR was failing to take any action to prevent it. General Sefer Halilović admitted that ARBiH helicopters had flown in violation of the no-fly zone and that he had personally dispatched eight helicopters with ammunition for the 28th Division.
