MYSTERY FLIGHTS PROMPT TOUGHER UN MEASURES TO CONTROL AIR SPACE

SARAEJEVO, Feb 14 (Hina) - UN and NATO officials have still not uncovered the owners of aircraft said to have flown over Tuzla Sunday and Monday. UN spokesman, Colonel Gary Coward, said in Sarajevo today that the UN would take additional measures to control Tuzla air space after reports of mystery flights. The measures would be undertaken independently of NATO, Coward said. But Coward refused to elaborate on what exactly constituted the additional measures. Coward feared that leaking any details of the measures might threaten the desired effect of tracing the mysterious flights. Meanwhile the Nordic UN battalion, deployed in the Tuzla area, has claimed that they clearly heard, and twice at that, sounds of transport- and combat-planes. These allegedly dubious flights were not registered by AWACS, high-grade radar systems used in the "Deny Flight" operation to monitor the sky over Bosnia round-the-clock.
