Syria closed its airspace to all traffic for a short time as three U.S. warplanes approached, the Turkish newspaper Milliyet said. Turkish Foreign Ministry officials confirmed that they were notified of the Sunday closure. The newspaper report said the three U.S. warplanes were over a Turkish town near the Syrian border when Damascus made the decision. Syrian authorities apparently feared an attack in the wake of British accusations of Syrian involvement in an attempt to place a bomb on an Israeli airliner. An American spokesman in Ankara had no comment on the report, which came as U.S. warplanes were holding a major exercise in eastern Turkey.
