zone. Because of the Serb compliance, NATO ceased its operations around Goražde. Sarajevo In February 1994 (when air strikes were originally threatened), NATO had created a heavy weapons exclusion zone around Sarajevo, and collected weapons at a number of sites. On 5 August, the VRS seized several weapons from the Illidža Weapons Collection site in clear violation of the exclusion zone agreement. During the seizure, Serb forces injured a Ukrainian UNPROFOR peacekeeper. In response to the attack, the UN once again requested NATO air support. Two U.S. A-10 aircraft repeatedly strafed Serb targets, and the Serbs returned the seized weapons to the collection site. On 22 September, UNPROFOR again requested NATO air support in the Sarajevo area after Serb forces attacked a French armored personnel carrier. In response, two British SEPECAT Jaguar aircraft struck near a Serb tank, destroying it. Banja Luka incident On 28 February 1994, a NATO Airborne Early Warning aircraft flying over Hungary vectored two US F-16s to an area south of Banja Luka, where six J-21 Jastreb and two J-22 Orao were flying back to their base after bombing the "Bratstvo" military factory at Novi Travnik, in blatant violation of the non-fly zone. Four Serb aircraft were shot down and another crashed while trying to escape in low-level flight. This marked the first combat mission in NATO's history. Attack on Bihać, bombing of Udbina and hostages In October and November 1994, during the Siege of Bihać, the Muslim-Croat Federation launched a large offensive around the town of Bihać, in far northwestern Bosnia. The Serbs soon launched a counterattack, and in support of their operations, launched air strikes with aircraft based at a former JNA military airport in Udbina, south of Bihać, located in the Serbian Krajina in Croatia. The Serb aircraft dropped napalm and cluster bombs. Although most of the ordnance came from old, unreliable stocks and failed to explode, the attacks were a clear violation of the no-fly zone, and a challenge to NATO. NATO immediately looked for ways to respond, but its forces were not permitted to carry out operations in Croatian airspace, and due to Bihać's proximity to the border, Serb aircraft could attack into Bosnia, then cross back into Croatia before being intercepted. As such, NATO was powerless to stop the incursions. In recognition of the situation, the Security Council passed Resolution 958, which allowed NATO aircraft to operate in Croatia. On
